TWO SMALL GIT TWEAKS

This is the last of a set of releases intended to ensure npm's git support is robust enough that we can stop working on it for a while.

• 394c2f5 Switch the order in which hosted Git providers are checked to git:, git+https:, then git+ssh: (from git:, git+ssh:, then git+https:) in an effort to go from most to least likely to succeed, to make for less confusing error message. (@othiym23)
