RunAfterPendingVideoFrames is used to make sure VideoFrameFactoryImpl
pipeline is ordered and the callback is run after all pending
CreateVideoFrame is done. For this purpose it RequestImage() with the
same ImageSpec as last request and waits for request to complete.

It is possible that RunAfterPendingVideoFrames is called before any
CreateVideoFrame calls and so ImageSpec isn't initialized yet. This CL
fixes this by skipping RequestImage() in this case, as there should be
no pending CreateVideoFrame.
