start running serialization view tests again

[mjkkirschner]

Purpose

Nunit3 has different behavior when it comes to catching assertions than nunit 2 - they still mark the test a failure, so we ignore the results of a few different nodes whose behavior actually changes depending on where the graph is executed from.

LGTM, Should we create a follow-up for the remaining ones?

[mjkkirschner]

sorry @sm6srw did I miss some failures?

[sm6srw]

@mjkkirschner No, it was late last night. You are good.

adds 30 minutes to the tests, but it passes everywhere - if we want to run less of these for faster test runs in the future I'm okay with that.
