Fix Fairteiler posts for non-followers
Closes #467 (closed)
What does this MR do?
It removes the mayFairteiler() function, that always returned false if one was not a follower of the Fairteiler, and all the places it has been called.
mayFairteiler() has been introduced in b1132e50 and has been called before the bell notifications for Fairteiler followers have been triggered. That caused bells not to be sent for fairteiler posts authored by non-followers. I think this is incorrect behaviour; that's why I removed the function completely. If you think, non-followers should be able to post, but their posts should not trigger bell notification being sent to the followers, I'll revert that.
Later, I called the function in WallPostPermissions too, thinking that it would contain correct permission logic. That caused non-followers not being able to submit Fairteiler posts any more.
