The change a086f921a72 (submodule: decouple url and submodule interest,
2017-03-17) enables us to do more than originally thought.
As the url setting was used both to actually set the url where to
obtain the submodule from, as well as used as a boolean flag later
to see if it was active, we would need to keep the url around.
Now that submodules can be activated using the submodule.[<name>.]active
setting, we could remove the url if the submodule is activated via that
setting.
In preparation to do so, pave the way by providing an easy way to see
if a submodule is considered active via the new .active setting or via
the old .url setting.
