Fix issue of add/remove a frame at a scene before all key frames of a layer.
When you added or removed a frame at a scene before all key frames of
a layer, frameline was not updated correctly. It seems nothing
happened, but domview is updated. This changeset fix this issue by
correcting logic for boundary case.
