Fix #196 The way to do collection discovery described in http://stackoverflow.com/a/11673483 doesn't work well with Radicale: 1. current-user-principal returns /user/calendar.ics/ 2. PROPFINDs asking for calendar-home-set will return the URL that was used in the request, which is still /user/calendar.ics/ 3. The final PROPFIND with Depth: 1 is supposed to list all collections, but because the request is done with a collection URL, Radicale returns the items for the "calendar.ics" collection which might or might not exist.
