Matthew Fritze 6efea1e624 Update Settings search result unique ids
- SearchResult stableIds are now DocIds from the database
- DocIds are data reference key's hash, when the key is not
empty or null
- Otherwise, DocIds are a hashcode from a set of fields.

Change-Id: Id36f7bf4ceaaa3a2bd326ecafbfe97fd0b247df2
Fixes: 37327194
Test: make RunSettingsRoboTest
