Update latency compensation when sends are added or removed
Previously only adding an aux-send triggered a graph-reorder but copying or deleting sends did nothing. Adding/removing an aux-send may not even change the graph, but both upstream/downstream latency can change and delaylines need to be configured (which is done by calling update_latency_compensation with force_whole_graph = true). This fixes an issue with incorrect initial latency compensation after copying a send (any later change to connections will correctly recalculate it).
