title: Unsupported URL protocol in git provider error
body: <p>I have two separate PCs that connect to the same Gitlab repo. Both running Visual Studio Update 3 and using Team Explorer with Git. On one PC, I have no problem updating the project and then pushing the commits to the remote repo. On the other PC however any operation (push or fetch or sync) will fail with an <code>Unsupported URL protocol</code> error, although originally I managed to clone the repo. I suspect it doesn't like something in the connection string, since I can commit and sync the repo using command line git (version 2.9.2 so fairly recent). What is the cause of this error and is there a workaround?  </p>
