Lance Stout d8d9e8df16 Fix stanza clobbering when replying to errors.
If a stanza handler raised an exception, the exception was processed
and replied by the modified stanza, not a stanza with the original
content.

A copy is now made before handler processing, and if an exception occurs
it is the copy that processes the exception using the original content.
