There's a bug here that I'll fix in a v3. We need to have a implicit_*
variant for dst_oid as well. Currently this will be buggy and check out
origin/<branch>, but then check the index out to the tree of whatever
the last <someremote>/<branch> we iterated over was.
Easiy fix and I already have it locally, I just want to improve some of
the testing. I missed it because in my tests I'd just re-add the same
remote again, so the trees were the same.
