This is a regression introduced by 74703a1e4d (submodule: rewrite
`module_list` shell function in C, 2015-09-02).
Add a test to ensure we list the right submodule when giving a specific
path spec.

I developed this on top of current origin/master, though I can backport it
to 2.7 as well if desired.
I do not remember the cause why we started to ignore a common prefix.
Thanks,
Stefan
