[Media Router] Check for stamped first run flow before getting height.

[Media Router] Check for stamped first run flow before getting height.

Currently, shownComponentsChanged_() assumes the first run flow has been stamped before getting the offsetHeight. This is not always the case if the first run flow has already been acknowledged but the current view of the media-router-container is modified.
