 In 2.6.0mtn, when a buddy's alias is set immediately after the contact is
 added to the MSN account, a crash occurs:

 {{{
 Thread 0 Crashed:
 0   libpurple                           0x008341a8 msn_update_contact +
 844
 1   libpurple                           0x00840740 msn_alias_buddy + 60
 2   libpurple                           0x0078eb50 serv_alias_buddy + 260
 }}}

 msn_userlist_find_user returns NULL, which the function tried to access as
 though it weren't.

 I should know better to use wiki formatting.
