retest button is broken in non-obvious way on incomplete revision
When the series is incomplete, the retest button is there, but it broken - clicking it results in a fail.
This is because the revision number component is missing from the URL, e.g.:
instead of https://patchwork.freedesktop.org/api/1.0/series/50443/revisions/5/newrevision/ we get https://patchwork.freedesktop.org/api/1.0/series/50443/revisions//newrevision/
Which results in 405 Method Not Allowed response.
