PYTHON-4925 Fix test bugs in $$matchAsDocument and $$matchAsRoot

Also:

• Fixes a bug where the driverConnectionId field was missing from "server heartbeat failed" log messages.
• Avoids sending "upsert": False since various client.bulkWrite spec tests assume this field is only sent when it's True.

Implementation for mongodb/specifications#1706

This should be ready for review now, I'm expecting the tests to pass.
