This regression was introduced in 74703a1e4dfc (submodule: rewrite
`module_list` shell function in C, 2015-09-02), as we optimized
the new module listing for performance by first checking whether it is
a git link instead of feeding it to match_pathspec.
By switching these two commands we get the same behavior as before,
i.e. in an empty repository this still breaks, but if there are files
but no submodules this works.
By reversing the order we also revert an accidental feature. If you had
a README file in a repository, you could do
git submodule deinit "READM*"
and it would report that there is no submodule matching the "READM*"
path spec.

Ok, let's try again. This is what I understand is the best bugfix for
2.8 and below. (This patch was developed on top of 2.7.4)
As discussed we want to have a better solution in the future, which
may included having the --unmatch-ok flag, but that is not in the scope
for now.
Thanks,
Stefan
