Context (projection_fakes_internal_event.js):

• 2 shard sharded cluster
• projection_fakes_internal_event.test collection is being created and 5 documents are inserted. It's placed on shard 1
• we open a collection change stream at time (1, 1)
• consult placement history for timestamp (1, 1)
• retrieve placement history in form of shard0 (initialization marker data)
• wait forever and don't observe any events, because the events for that database are present on shard 1, but no event is emitted on shard 0 for us to update the set of tracked shards
