Log Message:
-----------
Bugfix #23979: FCurve.keyframe_points.add(..., replace=True)

... fails if there were no keyframes in the curve yet. Was a missing null-check for case when no keyframe array is created.

Also, changed the description for the "replace" arg to better reflect what it really does.
