Fix IME insets not apply hidden when switching focus in diffrent users

Normally, the focus window will apply the IME visibility state to
WindowManager when the IME has applied it. But it would be too late
when switching IMEs in between different users. (Since the focused IME
will first unbind the service to switch to bind the next user of the
IME service, that wouldn't make the attached IME token validity check
in time)

As a result, we have to notify WM to apply IME visibility before
clearing the binding states in the first place.
