Config parser can't handle invalid remote configurations

The git config parser throws when a git config file has entries like:

```
...
[remote "github-for-unity-a17860a2-9122-489c-825a-46aa51bf1a0f"]
[remote "github-for-unity-a17860a2-9122-489c-825a-46aa51bf1a0f"]
[branch "fixes/history-view-null-check"]
        ghfvs-pr-owner-number = "github-for-unity#221"
        merge = refs/heads/fixes/history-view-null-check
```
