Prior to this change, an operation such as git submodule add, init or sync produced the wrong result when the origin URL of the supermodule was itself a relative URL.
The issue arises in these cases, because the origin URL of the supermodule needs to be prepended with a prefix that navigates from the submodule to the supermodule so that when the submodule URL is concatenated, the resulting url is relative to the working tree of the submodule.
This change ensures that this is done for add, sync and init.
