tests: consolidate test-push-http.t and test-push-http-bundle1.t
These tests were initially copies of each other. Now that we have
#testcases support in .t tests, we can consolidate them.
The changes to test-push-http.t reflect the differences between that
file and test-push-http-bundle1.t.
The variances in phases push behavior are the biggest differences.
The test will be updated in a subsequent commit to make the differences
more clear and to expand test coverage. For now, let's just port
the differences verbatim to get the tests consolidated.
