Fix response streaming in case of error

[lightZebra]

OutputStream will not be closed in case of error so underlying server could handle it properly. Fixed issue: termination chunk was send after streaming interruption by error.

Fixes #420.

@weavejester do we need to changes anything else?

[weavejester]

The code looks fine. Could you change the commit message to:

Remove closing of response stream on exception

When an exception occurs, the response output stream should not
automatically be closed, as that prevents the adapter from changing the
output of the stream to handle the exception.

Fixes #420.
