Trigger deltaUpdate in ContactsIndexerUserInstance
1) Create and initialize ContactsIndexerImpl in ContactsIndexerUserInstance
2) trigger the delta update in ContactsIndexerUserInstance to make it work
end to end. Namely if contacts are changed on the device, we will see
those changes reflected in AppSearch.
3) correctly set and persist last delta update and delete timestamps

Also did manual test on device with this feature enabled:
1) added 5/100/1000 contacts
2) wait until indexing finishes while monitoring the cpu and memory
usage. No major issue found
