topic: add the changelog argument to branchinfo()
47c03042cd1d in core added a changelog argument to revbranchcache.branchinfo()
and we wrap that function in topic extension. So let's add this optional
argument in topic extension too.
#!/bin/sh
. $TESTDIR/testlib/pythonpath.sh
# This file holds logic that is used in many tests.
# It can be called in a test like this:
# $ . "$TESTDIR/testlib/topic_setup.sh"
# Enable obsolete markers and enable extensions
