Fix not invoke setImeWindowStatus when unlocked by PIN lock

CL[1] removed setImeWindowStatatus call in showSoftInput()
since showWindow() has a call.

Howerver, the call invokes only when the IME visibility has changed.
It overlooked the case that when the screen unlocked by PIN
lock, since the focused app and IME visiblity is the same, so
the setImeWindowStatus in showWindow() doesn't invoked.

When then keyguard shown, IMMS side will invoke updateSystemUiLocked to
update navbar icon as invisible, so after the user unlocked, user won't
see the navbar icon set visible back.

As the result, we still need setImeWindowStatus called in showSoftInput
to fix this case.
