🎯 Review Instructions

Connect a local VAST to a VAST running the same plugins specified in a different order and notice VAST no longer warns unnecessarily.

I don't have a setup to test, but looking it the code it seems pretty safe to say that it should work.

Relying on the order being setup during startup is a very implicit way of doing this, but long-term the issue should resolve itself anyways as soon as record comparisons become order-independent.

A better fix would probably be to use a stable set for this with a custom equal_to function object, but that is far more than we need to fix this before the release. I'll write a story for that.
