tweak: do NOT clean up the error recovery info until the parse is done:

- DO NOT cleanup the old one before we start the new error info track: the old one will *linger* on the error stack and stay alive until we  invoke the parser's cleanup API!
- `recoveringErrorInfo` is also part of the `__error_recovery_infos` array, hence has been destroyed already: no need to do that *twice*.
