Effect plugins: don't set modified flag on control changes

Fixing a bit of a silly error made by me, all control changes on my effect plugins were flagging the project as modified, which is annoying with automations etc. So I'm disabling it. Maybe later we can have flagging only when knobs are modified manually.
