Windows: Trying to join to a multicast group as a receiver with specific interface always uses default interface

To reproduce:

• computer with multiple NICs, connected to multiple networks
• modify multicastreceiver example by specifying an interface in:

      udpSocket->joinMulticastGroup(groupAddress, <interface>);
  

• run multicastsender on some other machine on those networks

For some reason it still listens the default interface
