Object.deliverChangeRecords should remove the observer from activeObservers

To preserve ordering guarantees during end-of-turn delivery, Object.deliverChangeRecords needs to remove the delivered-to observer from the list of active observers.

The added test demonstrates this behavior.

lgtm. good catch.

LGTM.

Btw, nit: can we perhaps rename 'activeObservers' to 'pendingObservers', in
analogy with pendingChangeRecords? I somehow find 'active' a bit misleading.

Renamed.
