Log Message:
-----------
Crash when animating transform-related properties from none to none

Reviewed by Simon Fraser.
Animating transform-related properties (translate, rotate, scale) from none
to none would crash in WebCore::blend (in AcceleratedEffect.cpp) because
the from and to value is null. Account for this case by returning base
when from/to is null. Also simplify the logic a bit.
