When an error occurs, the MantisBT error handler clears all callbacks
(EVENT_GROUP_ACCESS_HAS_BUG_LEVEL) with event_clear_callbacks().
When callbacks are cleared, event_signal returns the second parameter
that we have given to it. After that, $p_user_id becomes an array and
we don't want that so we put back the initial $p_user_id in it.
