set the interactive action to NULL before doing its cleanup phase

if the cleanup ends up cancelling the "current interactive action", it would
cause the end function to be called again, which sucks.  for instance if the
cleanup function uses the Focus action. this prevents the unwanted loop
into the interactive action cleanup.
