Swapping `git add <submodule>` to `git submodule add <submodule>`
in a previous patch created a .gitmodules file with multiple
submodules pointing to the same path in certain tests. Fix tests
so that they are run on the original added submodule rather than
a separate manually configured submodule.
Doesn't "git submodule add" have a way to give a specific name other
than the default taken from the path? If "git add sub" is converted
to "git submodule add --name subname ./sub", wouldn't these changes
become unnecessary?
