Fixes #8474.

Summary:
A rapid sequence of events for a single document, within the window of a single global snapshot, can result in delayed limbo resolution for that document.

The events sequence leading to the delay are:

  1. A watch change event (e.g. add, remove, or update document for any target), where the event contains updated document data.
  2. A watch change event (e.g. delete or remove document from target), where the event is the response to limbo resolution for the same document as event 1.

When these two events occur within the window of a single global snapshot, the limbo resolution associated with the delete event, is delayed until the next global snapshot.

    Consolidate CI test output into a single string (#8489)

    * Consolidate CI test output into a single string

    Having CI test process stdout and stderr in a single string makes it
    easier to read when looking through failures, since you can see the test
    output alongside the error messages.

    Without this, any stderr output written during a test will be captured
    seperately from the test output, so when we then log it after a test
    failure, we can't tell which test logged which errors.

    * Prefix stdout and stderr output
