tests/sources/git.py: Testing the git:invalid-submodule warning

   o Test that it is not triggered in show before fetch, because we
     don't know the submodules yet so we cannot know if they are
     valid or not.

   o Test that it is triggered by a fetch command

   o Test that it is triggered by `show` after having completed a
     fetch command, since now we have the repository and know which
     specified submodules are invalid

   o Test all of this under warning or error conditions (parameterized
     for fatal-warnings)
