Subject: [PATCH] import: github: Do not update URI for packages using git-fetch.

From: Arun Isaac <[email-masked]>

During `guix refresh PACKAGE`, the source URI for packages using
git-fetch need not be updated. It can be returned unchanged, as it
is. The attached patch does that.

As a side issue, without this patch, git-fetch packages that do not have
a source URI ending in ".git" are not updated correctly using `guix
refresh PACKAGE`. See the package emacs-evil for an example.

Subject: [PATCH] import: github: Do not update URI for packages using
 git-fetch.

* guix/import/github.scm (updated-github-url): Return the unchanged source URI
for packages using git-fetch.
[updated-url]: Do not handle URIs which end with ".git".
