      Description

      A transaction that creates a new unsharded collection will fail when attempting to insert data:

      >>> with client.start_session() as s, s.start_transaction():
      ...     client.db.command('create', 'test', session=s)   # Succeeds
      ...     client.db.test.insert_one({}, session=s)   # Fails
      ...

      This reproduces consistently on 4.5-latest, even after the fix in SERVER-47472:
