Log Message: ----------- IRC_SERVER: Make sure that the client sent a prefix

The SERVER command is only valid with a prefix when received from other servers, so make sure that there is one and disconnect the peer if not (instead of crashing ...).

This obsoletes PR #275.

Thanks Hilko Bengen (hillu) for finding & reporting this as well for the patch & pull request! But I think this is the "more correct" fix.
