obsexchange: make compatible with some unreleased 4.5 versions

We don't generally care to be compatible with unreleased versions of
hg, but this is just a one-line change to be compatible with a range
of commits before 158d4ecc03c8 (wireprotoserver: move all wire
protocol handling logic out of hgweb, 2018-03-08), so hopefull it can
be worth it.
