AOSP/Messaging - update the Messaging version to target P (28) or higher. Fixed tests in messagingtests. All tests pass/work.
+ ParticipantRefreshTest - Added UIIntents and FakeDataModel. Fixed the errors in the data verification.
+ GetOrCreateConversationActionTest - conversation already exists (changed the assert).
+ ConversationFragmentTest - Return mockDraftMessageData even if createDraftMessageData is called with null argument.
  These tests weren't passing witout any changes (they weren't even starting without the target version update).
