 Description   

after the underlying DocumentSourceCursor fetches a new batch, this stage should retrive the latest events from the multicast change collection. it will then merge child documents with the events from the multicast collection and throw TennantMigrationCommitted if it hits a split or merge no-op.

if the multicast change collection isn't ready we can just used an unmanaged collection to unit test
