Crash at adding folder which is git repo by itself

[kulik]

Describe the bug
it's a crash when you stage folder which has .git folder inside, and still not a git-submodule
To Reproduce
Pre conditions. init repo, with git init, copy the other git repo inside.
Steps to reproduce the behavior:

1. open gitui
2. select coursor on folder which is repo
3. hit enter
   crash

Expected behavior
At least nothing should happend
the best result it's to suggest to add it like git submodule.

Desktop (please complete the following information):

• OS: Linux ubuntu
• gitui v0.5.0

Additional context

gitui
Error: git error:invalid path: 'nginx/lua-lib/lua-resty-hmac/'; class=Index (10)

Caused by:
invalid path: 'nginx/lua-lib/lua-resty-hmac/'; class=Index (10)

where lua-resty-hmac/ - it's git repo by itself

Hey @kulik thanks for reporting this. Indeed this should not crash. but what is the expected behaviour? does the git cli support checking in this repo into the outer repo?

[kulik]

thereis a ugly way - just to comit it straight as it. i wouldn't expect that, probably it's normal for some cases with skiping .git folder. but the briliant way is
https://git-scm.com/book/en/v2/Git-Tools-Submodules
it's possible parse origins of internal git repo, and suggest user to add it as it or as submodule with current HEAD positio of it's parsed origin url, or suggest to enter other url but preserve HEAD

@kulik I cannot even figure out how to commit a .git subfolder using git-cli. it is simply ignored. so I am tending to simply swallow the error and ignore it in gitui aswell. submodules are a different can of worms

this is what should happen now:
