Prevent ANR when app is terminated abruptly
When app is forced stop, the removeImeSurface flow
from DisplayImeController will be dropped in IMMS
and IMS because some fields (IMMS#mShowRequested,
IMS#mShowInputRequested..etc) still remain previous
state. The launcher cannot receive keyevent at that
time since IME surface remain and cause ANR.
Calling hideCurrentInputLocked() to hide the IME
surface when a IME client is removed.
