Jens Stutte 0f4192786c Bug 1738185: Update the error handling in the mediator around mReady status. r=mccr8 ... mReady is false both before nsWindowMediator is initialized and after it observed xpcom-shutdown. In the latter case we can still receive Javascript calls as the service is not yet unregistered. We want to ensure that: - we cannot register new windows anymore (this was already the case but we want to assert, too). - we do not throw while asking for enumerators even late in shutdown, returning an empty enumerator. - we assert on other late calls (but keep returning an error in non-debug).
