 Readds the last finished speaker user (the highest `end_time`) to the list of waiting speakers. This fails, if
 - There is no last finished speaker
 - The last finished speaker is already a waiting speaker with the same point-of-order status
+- The speech state of the last speaker is `interposed_question` and there is no unfinished speaker
 
 The new waiting speaker gets the weight of `min-1` of all waiting speakers or 1, if there are no waiting speakers.
