Removing an animation target during animation crashes WebKit

SVGAnimationElement does not hold its target in a RefPtr.  Thus if you remove
the target during animation, WebKit will crash.

A simple fix is to remove the m_targetElement cache.  The only problem then
becomes un-applying any animations once it's no longer the target of
animations.  Perhaps SVGElement should override setId to clear any animVals on
the object.  Not sure.  That can be tracked with a separate bug after the crash
has been fixed.
