Summary

Some drivers, notably the asynchronous Java Reactive Stream driver, can end up sending extra getMore commands for change streams.  This is causing some current unified tests for change streams, which expect an exact sequence of command events, to fail.  The request is to add ignoreExtraEvents to the following tests: 

• Test with document comment
• Test with document comment - pre 4.4
• Test with string comment
• Test that comment is set on getMore
• Test that comment is not set on getMore - pre 4.4
