Not sure if we will keep this going forward (there will likely be an opaque tab control on the notifications overlay similar to options) but let's go with this for now.
1) waiting for loading to finish so Drawables are all present to do asserts on
2) fix NullRef in ResultPage because of removed line in DummyWorkingBeatmap (author one)
I've find "You've retried xx time(s)" message that something weird.
That is not displayed pause overlay and only see count on FailOverlay
I change code that PauseContainer.Retries property can be set call-back function.
