We want to verify that transactions interact with collection creation operations correctly. To verify this, we should test the following case:

1. A transaction writes to a collection C that doesn't exist. In a different session, collection C is then created. Verify that the transaction can then write to collection C and commit.
2. A transactions writes to a collection C that exists. A client in a different session that tries to create C should fail.

*Note: when writing these test cases, we should verify any behavior that differs from what is described above and make sure it matches the desired/expected behavior.
