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.
#require docutils gettext
Error: the current ro localization has some rst defects exposed by
moving pager to core. These two warnings about references are expected
until the localization is corrected.
