Subject: [PATCH 05/30] Do not check the release list if a Terraform is already
 installed (fixes #395)

Today, tfenv checks the Terraform release list when running
`tfenv install`, even if the requested Terraform is already
installed. This fixes an issue where a script containing
`tfenv install` becomes inoperable even if Terraform is installed,
but releases.hashicorp.com is down.

See #395 for more information.
