bookmark: make the search for divergent names more robust

We translate the "url we update from" and "the url in the config" into their
canonical representation. This is useful for urls that have multiple equivalent
forms:

  /foo/bar/ == file:/foo/bar/ == file:///foo/bar


eg: hg pull --config path.bar=/foo/bar/ file:/foo/bar
