Prevent errors if the 'resize' event is fired before the eventBus has been initialized

Browse Source 
When opening a PDF file that triggers the browser fallback bar in the Firefox addon/built-in version, e.g. http://web.archive.org/web/20110918100215/http://www.irs.gov/pub/irs-pdf/f1040.pdf (with forms *disabled*), and then reloading the document an error can be thrown.
The reason is that displaying the fallback bar triggers 'resize' events, and they can arrive *before* the viewer has had a chance to run all the necessary initialization code.
