test-hgweb-annotate-whitespace: make test compatible with chg
D946 fixed a bunch of tests which had the same root cause. Please see
that for details. This seems to be one of the newer tests which fails because
of the same reason.
Test Plan:
Ran the test 'test-hgweb-annotate-whitespace.t' with and without the
'--chg' option.
