We do already have the unfortunate precedent of using "test_must_fail
test_alternate_is_used"
(and it was partially included by me in 31224cbdc72 (clone: recursive
and reference option
triggers submodule alternates, 2016-08-17), further used in
bf03b790471 (submodule--helper:
set alternateLocation for cloned submodules, 2016-12-08).

I think it is the wrong approach though, as the test_must_fail only ensure that
*something* doesn't return success. Usually we use it with
"test_must_fail git ..."
to ensure we properly error out on user requests, that are impossible
to fulfill in
the current implementation.

For this test case I'd suggest we rather test that the no alternate is setup,

    test_path_is_missing
super/.git/modules/sub-dissociate/objects/info/alternates

as that tests the correctness of the --dissociate option?

Thanks,
Stefan
