Title: Fixed group converterNode resource leak.

When creating `AEChannelGroup`s, `converterNode`s are sometimes created alongside the `mixerNode` for each group. However, in `releaseResourcesForGroup:`, only the mixer node - not the converter node - is removed from the graph, leading to a resource leak if a number of groups are created and destroyed over time.
