Bypass connection point proxies when possible

This greatly improves compatibility with VST3 plugins in Ardour and
Mixbus. Most notably the FabFilter plugins would previously freeze when
having the GUI open while duplicating or inserting new instances.

 - Prevented latency introducing plugins VST3 from causing **Ardour** and
   **Mixbus** to freeze when loading the plugin. This for example prevents
   _Neural DSP Darkglass_ from freezing when used under those DAWs.
+- Fixed _FabFilter_ VST3 plugins freezing in **Ardour** and **Mixbus** when
+  trying to duplicate existing instances of the plugin while the GUI editor is
+  open.
 - _PSPaudioware InifniStrip_ would fail to initialize because the plugin expects
   the host to always be using Microsoft COM and it won't initialize it by
   itself. InfiniStrip loads as expected now.
