Properly unload VST3 plugins
The InstrumentSelector keeps a PluginPtr reference to all
instruments. By default Ardour does not destroy the editor
at exit, So 3 instances of Instrument Selector can remain

 * TriggerClipPicker in the editor sidebar (owned by _editor)
 * TriggerClipPicker on the TriggerPage (owned by trigger_page)
 * SoundFileOmega (sfbrowser owned by Editor)

If a shared_ptr reference is retained, VST3 Module is not
unloaded at exit. This leads to issues with various plugins.
eg. Reason Rack does not terminate, Ardour hangs at exit.
