Fixed unit test and url parsing in lib install via git
Browse files Browse the repository at this point in the history 
Previously go-git accepted urls in the format:

  https://github.com/author/repo#ref

but now it refuses to fetch if the "#ref" suffix is present.
The new parsing utility returns the URL cleaned up of the reference.
