No git add option for new files

[Kwooda]

I updated to v8.7.1 in the Atom editor running under MacOS 10.13.6 and when I right-click on a new file, I no longer git a list of commands in the Git menu, but rather only see Diff Against Branch - which makes no sense since it's a new file that wouldn't exist in the branch. But I cannot add the file.

Steps to reproduce:

1. Create a new file in the Atom editor
2. Right-click on the file to get the context menu and select Git
3. Observe that there is no option to add the file
