Bugfix/incorrect context menu activation fix #8425

[Aiiaiiio]

This PR solves #8425

Note to reviewers

Context

In the scenario detailed in the bug report the "Free up local space" context menu item is deactivated, because the directory's pin state is online only. The pin state is checked in a non-recursive way, the pin state of sub-items are completely disregarded.

Solution

To solve this, I check the pin state recursively. This way the result will be "all hydrated", or "mixed" (according to contents) which will activate said context menu item.

Considerations

This idea might not be the best, because it introduces a performance issue. If the directory has a lot of sub items, the recursive check might take a long time. For this reason I attempted to make the recursive check slightly faster, however this alone won't solve the possible performance issue.
