Handle tempo-map changes in sync from the calling thread 

This is required to collect relevent undo/redo information, notably
automation-data changes from Playlist::update_after_tempo_map_change and
DiskReader::playlist_ranges_moved.

The realtime thread should not move regions to begin with, and debug
builds woudl also assert since no undo operation was started.
