submodule: fix relative url parsing for scp-style origin

Browse Source 
The function resolve_relative_url was not prepared to deal with an
scp-style origin 'user@host:path' in the case where 'path' is only a
single component.  Fix this by extending the logic that strips one
path component from the $remoteurl.

Also add tests for both styles of URLs.
