Change tolerances to a more realistic value for the CI tests

Use Case

The tolerances used in the CI tests are unrealistically small, typically 1e-12.

Problem

There is no valid reason for having such small tolerances. And we have had multiple instances of users using the CI tests as templates for their own simulations. This has caused those simulations to fail with convergence problems which in turn causes confusion in the user community.

Solution

I will change all of the tolerances in the CI tests to be more representative of the tolerances used in real simulations.

Alternatives considered

none
