.minecraft can no longer be a symlink

If .minecraft is a symlink to another folder (in my case another internal storage device), the launcher fails to start entirely, with various errors about missing files and translations.

Copying .minecraft to my home folder or mounting it to that location allows the launcher and client to start without issue.

Using a symlink worked in the previous launcher version, and would be preferable to a mount point or storing on my home folder directly.
