    do not include context to exception notification

    The wrap_exception decorator optionally emited a notification.
    Based on the code comments the original intention was not to include the
    context to that notification due to security reasons. However the
    implementation did included the context to the payload of the legacy
    notification.

    Recently we saw circural reference errors during the payload serialization
    of this notification. Based on the logs the only complex data structure
    that could cause circural reference is the context. So this patch
    removes the context from the legacy exception notification.

    The versioned exception notification is not affected as it does not
    contain the args of the decorated function.
