hgweb: always start graph with the revision in url

It is the same fix for graph command, as was recently for log. This makes the
specified revision be always on top of the graph view.
Before the patch, for example with repo having revisions 0, 1, 2, 3 and revision
in url being '2', all revisions were shown and the specified one wasn't
the first.
