All migrations are created with altering `sessions` table

[vv12131415]

Bug Report

Q	A
BC Break	no
laravel-doctrine/migrations version	1.1.10
Laravel Framework version	5.6.25
php version	7.2.7-1
MySQL version	5.7.22

Summary

When running artisan doctrine:migrations:diff it's always creates migration that contains changes to sessions table.

Current behavior

Running artisan doctrine:migrations:diff creates migration that contains SQL code below

The up addSql will look like

ALTER TABLE sessions CHANGE id id VARCHAR(255) NOT NULL

The down addSql will look like

ALTER TABLE sessions CHANGE id id VARCHAR(255) NOT NULL COLLATE utf8mb4_unicode_ci

How to reproduce

• create new laravel app
• add SESSION_DRIVER=database to .env
• run artisan session:table
• run artisan migrations:migrate
• make basic configurations to laravel-doctrine (use xml mappings)
• run artisan doctrine:mapping:import --namespace=Your\\Namespace\\ xml Your/Mappings/Folder
• run artisan doctrine:migrations:diff. It will create migration with session table changes.

My current xml for sessions table is

<?xml version="1.0" encoding="utf-8"?>
<doctrine-mapping xmlns="http://doctrine-project.org/schemas/orm/doctrine-mapping" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://doctrine-project.org/schemas/orm/doctrine-mapping http://doctrine-project.org/schemas/orm/doctrine-mapping.xsd">
  <entity
          name="Foo\Bar\Session"
          table="sessions"
          repository-class="Foo\Bar\SessionRepository"
  >
    <unique-constraints>
      <unique-constraint name="sessions_id_unique" columns="id"/>
    </unique-constraints>
    <id name="id" type="string" column="id" length="255">
      <generator strategy="IDENTITY"/>
    </id>
    <field name="ipAddress" type="string" column="ip_address" length="45" nullable="true">
      <options>
        <option name="fixed"/>
      </options>
    </field>
    <field name="userAgent" type="text" column="user_agent" length="65535" nullable="true">
      <options>
        <option name="fixed"/>
      </options>
    </field>
    <field name="payload" type="text" column="payload" length="65535" nullable="false">
      <options>
        <option name="fixed"/>
      </options>
    </field>
    <field name="lastActivity" type="integer" column="last_activity" nullable="false">
      <options>
        <option name="unsigned"/>
      </options>
    </field>
    <many-to-one field="user" target-entity="App\Doctrine\Entity\User"  inversed-by="sessions" fetch="LAZY">
      <join-columns>
        <join-column name="user_id" referenced-column-name="id"/>
      </join-columns>
    </many-to-one>
  </entity>
</doctrine-mapping>

My doctrine.php (showing only changes because it's almost similar) is

'managers'                   => [
        'default' => [
            'dev'           => env('APP_DEBUG', false),
            'meta'          => env('DOCTRINE_METADATA', 'xml'),
            'connection'    => env('DB_CONNECTION', 'mysql'),
            'namespaces'    => [],
            'paths'         => [
                base_path('Your/Mappings/Folder')
            ],
        ]
    ],

Expected behavior

Running artisan doctrine:migrations:diff gives error with message No changes detected in your mapping information. Like on screenshot

Perhaps it's better to ask this at doctrine/migrations? I'm not sure what's causing it
