(bug 53506) Protection disables feedback even if nothing is touched

By default & depending on the lottery settings, either aft-editor or aft-none
value is selected already.
When nothing is explicitly changed for AFT, no protection changes should be
saved to the database. Current situation will make every protection change
for regular page protection settings save the AFT settings (that may have been
left untouched)
