Bug 497833

SUMMARY
When setting a Default Keyframe Type to Smooth and adding a new keyframe, this keyframe is correctly set, but if I then cut the clip on that position, the 1st keyframe on the 2nd clip behind the cut, is still set to linear. Not sure

STEPS TO REPRODUCE
1. add a color clip to the project and the timeline
2. add Transform effect to color clip
3. set Default Keyframe Type to Smooth in the hamburger menu of the Transform effect option menu
4. add a keyframe to any postion, it will be added correctly as a Smooth keyframe
5. Press Shift+R to cut the color clip into two parts and check they keyframe type of the 2nd half of the clip
6. the 1st keyframe of the 2nd part of the clip is still added as "Linear" and not as Smooth

OBSERVED RESULT
1st keyframe of the 2nd part of the cut'ed clip is still added as "Linear" and not as Smooth

EXPECTED RESULT
1st keyframe after a cut is of the type set as Default in that moment / project
