use Editor::reassociate_metric_markers() before performing edits on tempo map

Browse Source 
The objects referenced by markers point to the copy of the map held by the per-thread ptr. But
the edits must be done on a writable copy of the map. ::reassociate_metric_markers() fixes
the references to use the writable copy, so that when we pass references to the objects in the map
to the writable copy, it will find them and modify them (rather then ones in the previous
generation of the tempo map)
