Towards fixing AU preset invalidation

This is a step in the right direction: first load the preset and
only if preset-loading was successful mark it as loaded.

This still does not properly unset "parameter_changed_since_last_preset".
AU signals "kAudioUnitEvent_ParameterValueChange" later in the event-loop.
