SceneFrameworkIntegrationTest does not need runCurrent

This does not switch to UnconfinedDispatcher.  Instead, it uses
several idioms to guarantee that runCurrent is called at the right
times:

- currentValue(StateFlow): this is already introduced, but now
  used consistently
- verifyCurrent(mock) for advancing tasks before verifying a mock
- currentValue { block } for clearly scoping other value retrievals
  that require advancement

Note: this accomplishes similar goals to ag/30532049, but with
fewer novel/bold/clever/intrusive patterns.
