Don't hide IME windows in transition player

IME windows, like wallpaper windows, have their visibilities
managed outside of the transition system. This means that
altering their visibilities can get us stuck in situations
that can't be undone. So, like wallpaper, just check and
skip explicit visibility changes on IME windows.

Test: messages in portrait, open ime, swipe to home, open
      messages in landscape, swipe home, open messages in
      portrait again (ime should be visible).
