Flutter logs should not attempt to filter the device list based on the current project, because it does not require a current project. Also fix disabled polling test
Fixes#47996Fixes#63550
Remove caching of FlutterView. Perhaps the FlutterView RPC might return an empty list if the VM is not quite up yet? We had some old logic to poll the flutter views RPC for up to 200ms. That doesn't seem like a great approach, so instead we could forgo it entirely and trust that either the views come up before the developer tries to interact, or we crash.
