Fix ops master pipelines
What does this MR do and why?
Describe in detail what your merge request does and why.
This spec was failing in ops master pipelines only. This is because the SLACK_TAG_URL
variable was only set on master.
This MR replicates the failure by setting the SLACK_TAG_URL
variable in the spec, and fixes it by stubbing the call to the notify_slack
method.
