[WINESYNC] Elegantly handle empty 'files' and 'directories' lists.

Expand on Timo's commit 4b5a55516.
    We may encounter cases where either the 'directories' or 'files' lists
    in the .cfg YAML files are empty, and we don't want the script to throw
    an exception in that case.

Furthermore, explicitly check for such empty lists when calling PyGit2
    index.add_all(...) function, because if it's called on a None or empty
    list, _all_ untracked files in the selected git repository get added,
    which is not what we want there.
