/**
 In certain cases WebDriverAgent fails to create a session because -[XCUIApplication launch] doesn't return
 since it waits for the target app to be quiescenced.
 The reason for this seems to be that 'testmanagerd' doesn't send the events WebDriverAgent is waiting for.
 The expected events would trigger calls to '-[XCUIApplicationProcess setEventLoopHasIdled:]' and
 '-[XCUIApplicationProcess setAnimationsHaveFinished:]', which are the properties that are checked to
 determine whether an app has quiescenced or not.
 Delaying the call to on of the setters can fix this issue.
