tests: add tests showing pulling from infinitepush works over wire
The current tests in test-infinitepush-ci.t showed that `hg pull -r <rev>` does
not work. Digging in code, I found that we have logic for pulling from
bundlestore without having client side logic. This patch adds test demonstrating
that pulling from bundlestore works when working over wire.
Pulling from bundlestore when the peer is a localpeer still does not works.
