Make user interfaces setup the default history adapter.

Make user interfaces setup the default history adapter.
This helps avoid some issues with the unit tests as well as gives us more
flexibility in the future.
Testing Done:
Ran the unit tests without issue. Ran Pidgin 3 with no existing config directory and verified that `history.db` was created properly.
