RESTRICT AUTOMERGE: Drop invalid data.

Drop invalid data when writing or reading from XML. PersistableBundle
does lazy unparcelling, so checking the values during unparcelling would
remove the benefit of the lazy unparcelling. Checking the validity when
writing to or reading from XML seems like the best alternative.

Test: install test app with invalid job config, start app to schedule job, then check logcat and jobscheduler persisted file
