Add scuba test for ui regression test. Covered cases: Speed Dial Tab, Contacts Tab, Call Log Tab, Call History UI.

Some code refactoring works for using database populating methods outside third party library and add new methods to clean contacts database and call log database.

Some golden images get uploaded.

Bug: 64022871
Test: Ran test cases on emulator and they got passed.
