purple: Implement 'close_request' to prevent segfaults after logout

Fixes trac bug 1190 ("Accepting SSL certs too late resets bitlbee-libpurple")

To reproduce:

1. Connect to server with self-signed ssl certificate (downgrading to libpurple 2.10.9 might be required to actually get the request)
2. Disconnect the account
3. Type "yes"
4. Acquire segfault.

Normally, query_del_by_conn() would handle this, but some requests have
no account context at all. Yeah, it sucks. This is how pidgin handles it.
