Trap handlers: adjust http error log

Log repr() of error because it's more conscience which makes it easier to
read the logs: in case of "e" there's additional
"Failure instance: Traceback (failure with no frames)" prefix which is
pretty useless because we won't have proper tracebacks for deferred anyway.
