[Evolution] Calendar substitutes "http://" for a "caldav://" address

[Cameron Adamez <cameron soycow org>]

Hi all,
I have Davical installed on a server. The URL that it uses for
calendars is in the format of caldav
://server.domain.name/caldav.php/username/calendar/

However, when I tried this in Evolution 3.16.4, I get the following
error:
Unable to connect to 'Unnamed': Cannot open calendar: Unexpected HTTP
status code 405 returned (Not Allowed) for URI: 
http://server.domain.name/caldav.php/username/calendar/

Is this a bug? Otherwise I will have to put in a redirect, but I feel
that is a bad idea.
