Drop FilterEffectBuilder::m_referenceFilters

Drop FilterEffectBuilder::m_referenceFilters

The job of this Vector used to be to keep a reference to the nested
"reference" filters, to avoid them being destroyed. The entire filter
graph/chain is now on the GC heap, and traced via
FilterEffectBuilder::m_lastEffect, so this additional reference is of no
use.
