upnpsoap: Work around some bad SearchCriteria

Browse Source 
The Control4 app apparently sends us badly-formatted SearchCriteria,
where they don't quote the upnp:class value.  So we'll add it in for them
if we detect that situation.

Fixes: SF Patches #173 (DLNA search query not as minidlna expects)
