submodule: move get_default_remote_submodule()

A future refactor got get_default_remote_submodule() is going to depend on
resolve_relative_url(). That function depends on get_default_remote().

Move get_default_remote_submodule() after resolve_relative_url() first
to make the additional functionality easier to review.
