* Fix ssh commands used in go SmartSubtransport
Before the fix, the commands sent were of the form:
```
git-upload-pack "/bar/test-reponame"
```
This resulted in the git server returning error:
`error parsing command: invalid git command`
This change replaces the double quotes with single quotes:
```
git-upload-pack '/bar/test-reponame'
```
* Update ssh.go
