Subject: [PATCH] Remove obsolete permission logic

flarum/core#1513 changes the post.edit permission so that it is only
granted if the user also has permission to reply to the discussion. This
means that explicitly revoking the edit permission is no longer
necessary, as it will never be granted in the first place.
