Editor::insert_time(), Editor::remove_time() handle automation
directly because time may be inserted to Routes without playlists
and combined undo-operation with marker, and tempo-changes.
However when the preference "automation_follows_regions" is enabled,
the playlist already moves the automation of region under any region
(possibly overriding future automation).
This resulted in possibly lossy, duplicate automation moves.
