ProcessingChain, nextError function

[smart--petea]

in runChain function there are a filtering on handler.name if it is supplied.
If a error is catched, processingChain instance will switch to error chain.
But nextError method does not support filtering by name.
Maybe to add it?

@smart--petea I don't see the need to have error handlers set to a particular sub-set of endpoints... can you provide a real world example where you would need this? Otherwise I'm happy with the current implementation.

For now, I can't find any.
But I think there may be the situation when user want to process the error in dependence of endpoint which generate it. A simple case can be the situation when the error branch is formed from one general handler for custom logger, second handle only for endpoint1 and third handle only for endpoint2.
