tests: don't push to our resources

A couple of tests use the wrong remote to push to. We did not notice up
to now because the local push would copy individual objects, and those
already existed, so it became a no-op.

Once we made local push create the packfile, it became noticeable that
there was a new packfile where it didn't belong.
