Log Message:
-----------
Bugfix [#29869] NLA editor keeps resetting my extrapolation mode every time I
edit a strip in the timeline
Tweaked the behaviour of the overwritting of extrapolation mode so that it is
less destructive when the problems it sets out to fix aren't likely to occur
(namely a top strip blocking everything below it due to extend backwards).
