cohrs 268b70e4e3 R759 - delayed were change could cause crash 
moveloop() sets a flag when a were/poly change should occur, but it
delays this change if the hero is Unchanging or cannot be interrupted (e.g.
praying).  However, by the time the change can be applied, the reason
may no longer be valid.  Reset the change indicator when this is the case.
Avoids possible strange polymorphs and were crashes.
