tests: update test expectations in pre-2.7.9 branch of this test

As far as I can tell this is the only spot that got overlooked. Rough
test methodology (run inside an hg working copy):

docker run --rm -v `pwd`:/hg -it debian:wheezy bash
apt-get update
apt-get install python python-dev build-essential unzip mercurial \
  wget libbz2-dev
make testpy-2.7.8

You could try and use the system Python, but it's 2.7.3 and has lots
of issues for hg these days that are not worth fixing.
