Avoid scary errors about tagged trees/blobs during git-fetch

This is the same bug as 42a32174b600f139b489341b1281fb1bfa14c252.
The warning "Object $X is a tree, not a commit" is bogus and is
not relevant here.  If its not a commit we just need to make sure
we don't mark it for merge as we fill out FETCH_HEAD.
