tests: add phase testing to test-push-http-bundle1.t stable

tests: add phase testing to test-push-http-bundle1.t

test-push-http.t and test-push-http-bundle1.t were initially copies.
Now that we have support for inline test variants, we can combine them.

One of the variances between the tests is testing of phase moving.
We add the missing code to test-push-http-bundle1.t.
