Exporting Camera Anims from Sequencer does not copy over tangents correctly

This appears to be tied to the integer time conversion. Converting in MovieSceneToolHelpers::CopyKeyDataToMoveAxis does not account for frame rate when converting tangents. I tested multiplying the tangents by InFrameRate.AsDecimal() and the results appeared correct. 

1. Create a new sequence
2. Add a camera to the sequence
3. Track two frames in the camera's X translation 
4. Edit the curve and add tangents that are readily apparent
5. Save the sequence
6. Right click on the camera node in Sequencer and select "Export to Camera Anim..."
7. Open the camera anim in Matinee and check the box on the X curve to show it in the curve editor
8. Fit zoom the curve editor to bring the curve into view

RESULT
The curve in Matinee will not look like the one is Sequencer.
