Comment 5 for bug 1098773

Ok, so trying to pipe dbusmock STDOUT into vala test was kind of a bust due to dbus-test-runner wrapping everything and not really supporting that feature. So instead, I submitted a patch to dbusmock that gives it two new dbus methods: one for clearing the call log, and one for querying the call log. Once pitti merges that we'll be able to move forward with improving the libfriends test suite.
