Allow user's group to be overriden in wordpress

This breaks the use case where a Cloudron user becomes
a Cloudron admin and this information is not propagated
to wordpress. For now, this has to be re-set manually
inside wordpress. Maybe this can be solved someday using
a "sync" task from the cloudron side for all apps.

Fixes #13
