tdf#76436 initialize maStartInterpolationValue.

Fix regrssion caused by 372c47309a192e67220913309fa1ccffdff8cde1,
where a from-to or from-by animation always interpolate with a
empty maStartInterpolationValue, ignoring original from value.

That also affect many animations, such as unexpected magnify effect
at the end of put-on-the-brake animation.
