Fix bug with values in cloned animators.

When a ValueAnimator is cloned, we correctly clone the underlying
PropertyValuesHolder objects and assign them to the new object.
However, we then put values into the new property map using the
old values instead of the new ones. This means that the per-property
animated values cannot be retrieved with the property names from
the cloned animator, because the map refers to the values of the
original object, not the cloned object that is actually being animated.
Fix is easy: just put the cloned values (which are already being created)
into the map.
