When duplicating a scene in any way other than Full Copy, the VSE data is (apparently) not copied along. To prevent dangling F-Curves, any animation of sequencer strips is removed. This is now done correctly for slotted Actions, instead of looping over the legacy `action->curves` field. Also the F-Curve RNA path that's being tested for is updated. Instead of deleting all F-Curves with `sequences` in the name, the code now correctly looks for `sequence_editor.strips_all`. Pull Request: https://projects.blender.org/blender/blender/pulls/135576
