Show unacknowledged toast message upon integration test failure

Often if a test fails and there's an unaknowledged toast message, that message will
explain why the test failed. Given that we don't display toast messages in
integration tests when they run (for reasons I can't recall right now), we need to
log it as part of the error message.
