This is follow-up work from SERVER-138287. Test at least the following cases:

1. Create and drop before adoption
   1. Both entries are adopted without validation.
2. Create before adoption, drop post-adoption
   1. The drop is validated as a container delete because the create is in the baseline.
3. Create + drop post-adoption
   1. Validated as normal. If within a batch, nothing is validated. If they are across batches, it's the same expected value as 2.

Use a separate it("") for legibility and set up the replica set again beforeEach to avoid dependent test cases.
