Fix persistent-https relative url resolving

Browse Source 
Previously, we would remove 'persistent-' then tack it on at the end
if it had been previously found.  However, this would ignore urljoin's
decision on whether or not the second path was relative.  Instead, we
were always assuming it was relative and that we didn't want to use
a different absolute url with a different protocol.

This change handles persistent-https:// in the same way we handled the
absense of an explicit protocol.  The only difference is that this time
instead of temporarily replacing it with 'gopher://', we use 'wais://'.
