Hide augmented inline suggestion if field value is changed to not empty

* For now filtering is not implemented for inline augmented autofill
  suggestions. So before this change,augmented autofill inline
  suggestions are displayed in the IME, and user starts typing, it's
  up to the IME to remove the suggestions.
* After this change, any text view value change event will be sent to
  framework autofill manager service, which will be used to hide the
  existing augmented inline suggestion.
* Caveat is that this may be less optimal for text heavy fields, such
  as the email compose field.
