Git: Determine if remote URL is being changed (#4243)

Browse source 
* Git: Determine if remote URL is being changed

Ansible reported there were no changes when only the remote URL for a
repo was changed. This properly tracks and reports when the remote URL
for a repo changes.

Fixes #4006

* Fix handling of local repo paths

* Git: Use newer method for fetching remote URL

* Git: use ls-remote to fetch remote URL

Using ls-remote to fetch remote URL is supported in earlier versions
of Git compared to using remote command.

* Maintain previous behavior for older Git versions

Previously whether or not the remote URL changed was not factored
into command's changed status. Git versions prior to 1.7.5 lack the
functionality used for fetching a repo's remote URL so these versions
will update the remote URL without affecting the changed status.
