url-mode: purge SHM pixmaps when destroying URLs

Browse source 
Unlike other surface types, the SHM cookie depends on the address of
each URL instance. This means if we enable, disable, and then enable
URL mode again (thus showing exactly the same URLs as the first time),
the URLs will have new addresses, and thus the old SHM pixmaps will
not get purged automatically.

So, manually purge them when destroying the URLs.
