Prevent duplicate tag push (#5748)

* we use the generated SHA of the assets repo within the tag name that is uploaded. This means that if a set of recordings has already been pushed, we won't attempt to push again and error out erroneously

* our tests were not cleaning up after themselves appropriately, update the integrationpushtests to actually clean up _all_ of their created tags.
