completions/git: fix support for path relative to current directory (#666)

Browse Source 
Continuing effort on https://github.com/nushell/nu_scripts/pull/617
which only auto-completes path relative to git root.

Before,

```
$ cd src/

$ git add <tab>
src/main.rs    Modified
README.md      Untracked

$ git diff <tab>
src/main.rs
```

Now it displays,
```
$ cd src/

$ git add <tab>
main.rs           Modified
../README.md      Untracked

$ git diff <tab>
main.rs
```
