rHG709b44f38ab9: changegroup: avoid creating empty changegroup part
Summary

Previously this check happened in the changegroup code itself. Since it's
refactor, this logic needs to move out to callers that care about it, such as
this one. Otherwise we get empty bundle devel-warnings in certain extensions.
