correct order of conditions, to avoid runtime errors

Hi @CrocHold, the change looks good to me. I just wonder what message made you run into the runtime error?

[CrocHold]

The runtime panic arose in my case when either the client or the server, deviates from following the latest handshake protocol.
It happened since pgbroker cant stay stateless at all times w.r.t. the next message arriving. (SASL's case)
And has to assume it & decide the next handler beforehand, storing it in context.

Got it, thanks for the explanation!
