Fixed missing auto-fill save callbacks on TextView.

It was accidentally broken during a previous commit where the CTS test
failure was ignored by a known issue being fixed in another change -
this change fixes both problems.

Bug: 33550221
Bug: 3380254
Test: CtsAutoFillServiceTestCases pass (for real now :-)
