Fix: https://github.com/mastodon/mastodon/issues/23644
As mentioned on that other thread, the issue arise when a `Status`
is created with SHAPE_TOO_COMPLEX making the instance variable ordering
unpredictable.
But we can sidestep that issue using code inspired from Shopify/paquito.
I added some code in the test environment initializer to cause this
issue to be reproduced and prove this change fixes it.
This code is also easily converted into a monkey patch.
