Detects modifications with submodules where there are none

[freijon]

Describe the bug
I have several submodules in my project. For some submodules, gitui keeps listing "M" modifications. When looking at the change, it shows: size: 0 B -> 0 B (+0 B). When I check with git status, there is nothing listed as modified.

Also, when I check the Submodules in gitui, all the submodules that are listed as modified have the following info:

Commit:
0000000000000000000000000000000000000000

This contradicts the information shown in the list where the correct hash is displayed (see screenshot below).

When I try to stage these phantom-modifications, I get this error:

Error
staging error:
git error:repository path '' is not owned by current user; class=Config (7); code=Owner (-36)
