fix: smarter git ssh override

[dennishenry]

Removing the overwriting of git ssh commands. This should not be done, and should be left to individuals using their own ssh configs. This breaks multiple usecases.

Removing git ssh command that overrides local git ssh commands.

CC @wraithgar possibly you can take a look as this issue is plauging many in the git/node community

Having the tests look at the actual os.homedir() git config makes me nervous. I don't think that's a very safe thing to be doing. We may want to combine tap.mock and tap.testdir to manually generate the files we want in tests and have os.homedir() return the testdir instead.

The code itself is looking good except for coverage, which my suggestion should hopefully fix.

@wraithgar I dropped using os.homedir() in the tests and applied all other suggestions. Let me know what you think now!

Thanks for sticking with this @dennishenry. Testing this is not easy. I think we're very very close here.
