Run ExceptionTracingTransformer until we reach a fixed point

The build 667 client has some ZKM exception handlers inside Jagex's
exeption tracing handlers. In a single pass, the regex is only capable
of matching the former and not the latter. The ZKM exception handlers
were removed, confusingly leaving Jagex exception handlers that do match
the CATCH_MATCHER regex.
