Prior to this change any attempts to set the app transition when the
screen was off would fail. That would cause the
SOFT_INPUT_IS_FORWARD_NAVIGATION flag to be incorrect when launching
an activity such as the alarm before the screen turns on.
Without SOFT_INPUT_IS_FORWARD_NAVIGATION in the correct state the
android:windowSoftInputMode="stateHidden" attribute would be
mishandled leaving an IME on the screen along with the alarm activity.
Fixes bug 10817166.
