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.
