Title: fix for BroadcasterCacheBase IllegalStateException

I use a custom BroadcasterCache that extends BroadcasterCacheBase, and I had an issue with atmosphere throwing:
java.lang.IllegalStateException: Request object no longer valid. This object has been cancelled.

The cause is a call to AtmosphereResourceImpl#getRequest(), which fails scope check.
