Fix testStressSwipeToOverview

- Finish recents controller to app rather than to launcher, to ensure taskbar state uses in-app configuration
- Also fix an issue when a gesture completes before onLauncherStart, which happens in 3 button mode. The error I saw in the test was:
java.lang.AssertionError: http://go/tapl test failure: Failed to receive an event for the state change: expected [Overview], actual: [Background, Normal];
Context: want to switch from background to overview, clicking Recents button; now visible state is Background
(This also accurately describes what I saw on the device, where the LauncherState went to Normal but the task was still running in the live tile)
