Merge "Fix bugs in context flushing"

Fix bugs in context flushing

The context flushing support in the context distributor can throw a
concurrent exception when a lot of context is active and a flush takes
place. This fix introduces proper synchronized access to the album maps.

In addition, there was an incorrect cast in the call to the persist() method
of the persistor.
