The test failed email contains this text:

All logs have been saved to /var/log/test_push/test_push.log on push
master. Detail debugging info can be found at go/push-to-prodAutotest
instance: localhost


The correct go link is "go/push-to-prod" not "go/push-to-prodAutotest".

Email sometimes eats newlines after links, so inserting a space after the link will probably fix this.
