Resolves: tdf#94249 do not remove broadcasters while iterators are in use
EndListeningContext holds BroadcasterStoreType iterators in its ColumnBlockPositionSet and collects broadcasters to purge them at the end. Removing broadcasters from ScColumn::maBroadcasters in between invalidates the iterators. Hence calling the "normal" EndListening() that removes a broadcaster when all listeners are gone while an EndListeningContext is in use is bad. Change-Id: Ibdd88469e91e6173ceff1f391c23ef7cb7c6f596
