[O] org-git-link 's open function org-git-open does not work correctly

[numbch...@gmail.com]

When I `org-store-link` in a local git repository file buffer, I got this
link:

[[git:~/.emacs.d/init/org-mode/init-my-org-hyperlink.el::develop@
{2017-06-24}::202][git:~/.emacs.d/init/org-mode/init-my-org-hyperlink.el::develop@
{2017-06-24}::202]]

Then I insert link into Org-mode buffer.
But when I open link with `[C-c C-o]`, it open git revision:
```
"/tmp/org-git-8fd5f4cf5d17479ead7b4329024860e84b6f2453/init-my-org-hyperlink.el"
```
This is not correct.
My current `HEAD` (command: `git show HEAD`) is:
```
commit 3cc7ee1792a7d7b8ddf51897f7b968af36bae745 (HEAD -> develop)
```

Thank you.

This is a contributed package. I'm Cc'ing the original author as he
might want to fix the issue.
