Remove node from runIntegrationTests (#2502)

Since `runIntegrationTests` is constructed in the engine it cannot use
assert. Switching assert to throwing an error I think is totally fine
here. It will still fail the test and we don't have that many legacy
scopes left and hopefully soon they will be gone as well.
