Pipeline could change the MEP unintended

                 Key: CAMEL-1233
             Project: Apache Camel
          Issue Type: Bug
          Components: camel-core
    Affects Versions: 1.5.0
            Reporter: Claus Ibsen
            Assignee: Claus Ibsen
            Priority: Critical
             Fix For: 2.0.0

When exchanges is processed from pipeline they result is copyed as input to the next exchange.
However during this copy Camel could potentially change the MEP to InOut. It should respect
the original MEP.

The flaw is in ExchangeHelper#copyResults

Fixing this also forces end users to use the correct send/request method on ProducerTemplate.
Now Camel will keep the MEP.
So if you are using send then its *inOnly* and then you the there is no result. Use *request*
for InOut MEP's.

This breaks a few of our own unit testing that was using the wrong method.
