Make sure that [email protected]:blabla urls' work in git source

The SSH style URLs don't work because we don't parse them correctly. We might have to introduce a third kind of URL (URL, SSH_URL and Path) when parsign a git source.

We can use a create like git-url-parse for normalizing Git repo URLs. However, it has some issues:

• Less dependencies? tjtelan/git-url-parse-rs#52
• Security vulnerability in the latest version tjtelan/git-url-parse-rs#51

Btw cargo has the same issue: rust-lang/cargo#1851
