I think this is a little less deterministic than the previous method of
listening to WebContents loading and checking them against the process manager;
any reason to migrate away from that tactic (using
WaitForExtensionViewsToLoad())?

At the moment when WaitForExtensionViewsToloaded() called,
ProcessManger::all_extension_frames_ doesn't holds the waiting extensions's
frames. because of that, CheckExtensionConsistency(line#104) failed.
 I think I can solve this problem with ProcessManagerObserver.

Done.
