ASAN_TRAP in WebCore::FilterEffect::takeImageInputs called from
WebCore::SVGFilter::apply

Reviewed by Said Abou-Hallawa.
The bug was caused by inputs to the FEMerge being size 0.
The original size was one, but the test script deleted the
child <feMergeNode>. This breaks the SVGFilter.
The fix is:
SVGFilterPrimitiveStandardAttributes::markFilterEffectForRebuild()
should clear m_effect even if the renderer is null.
This will force us to try to create a new one when
applying the broken SVGFilter.
