[flexi] Disable unneeded TransitionInteractorTests

When SceneContainer is enabled:
* FromLockscrenTransitionInteractor no longer handles
transitions to the bouncer (including swipes).
* TransitionInteractors aren't the source of truth
for surfaceBehindVisibility. See
WindowManagerLockscreenVisibilityInteractor.
* KeyguardState.PRIMARY_BOUNCER is deprecated,
disable running FromPrimaryBouncerTransitionInteractorTest
