Send empty response to IME when autofill session is destroyed
* Note that usually the session is destroyed when the focus is
already on a new input field in a different activity, so this
action will be no-op most of the cases
* But in case of augmented autofill service dynamically requesting
a new autofill flow, this works well on clearing the existing
suggestions on the current input field
