* Detect double stacks in the new format in tests
* Remove unnecessary uses of getStackByFiberInDevAndProd
These all execute in the right execution context already.
* Set the debug fiber around the cases that don't have an execution context
* Remove stack detection in our console log overrides
We never pass custom stacks as part of the args anymore.
* Bonus: Don't append getStackAddendum to invariants
We print component stacks for every error anyway so this is just duplicate
information.
