More logging for views filling

Add more log for views filling

1.  Add confirmed success. Confirmation is done via call by fetching
    autofillValue, or if app calls notifyValueChanged.
    If views aren't included in the success, it doesn't neccessarily
    mean that the autfilling failed. It could very well be that the app
    has implemented autofill functionality improperly.

2.  If for some reason, the autofill callback is for an autofill id that
    wasn't being tracked, we log count of such cases. We expect it to be
    0. This is only to catch such occurences, and investigate them, and
    fix tem later.
