Bugfix #20708: segmented bones don't work well with spline IK

There was a slight discreptancy between the tail values calculated on the spline before the head was displaced for the "chain offset" option and after this operation. However, only the original version got set.

This small difference resulted in B-Bones thinking that the endpoints of the bones were in places that they were not in, hence causing the curly patterns observed in the report.
