core: fix crash when reloading global dns configuration 
When reloading the configuration and there is a global DNS
configuration without domains, NM crashes in global_dns_equal()
because `old->domains` and `new->domains` are both NULL. Fix that.

  Thread 1 "NetworkManager" received signal SIGTRAP, Trace/breakpoint trap.
