[PATCH 6/6] Teach get_default_remote to respect remote.default.

[marcnarc@xiplink.com]

From: Marc Branchaud <marcnarc@xiplink.com>

Use "git remote default" instead of replicating its logic.

The unit test checks a relative-path submodule because the submodule code
is (almost) the only thing that uses get_default_remote.
