Properly defer effect slot changes

Note that this now also causes all playing sources to update when an effect
slot is updated. This is a bit wasteful, as it should only need to re-update
sources that are using the effect slot (and only when a relevant property is
changed), but it's good enough. Especially with deferring since all playing
sources are going to get updated on the process call anyway.
