non-deterministic tests are useless, since a failing test could not be reproduced unless the seed is known.

Concept ACK

Non-deterministic tests and the sources of non-determinism are documented in #15296.

👍
(also people are likely to re-run the tests before investigating deeply so won't learn anything from a random failure)

Thanks for merging.

Reviewers of this PR might be interested in reviewing #15327 which makes the test updatecoins_simulation_test deterministic.
