Fix sim tests so that they pass.

[dwedul-figure]

Summary of Bug

At least a couple of the sim tests fail due to insufficient funds. These failures might end up masking other, more serious failures.

Version

main

Steps to Reproduce

The following commands result in the following errors:

• make test-sim-after-import -> "panic: expected validator, not found"
• make test-sim-nondeterminism-state-listening-file -> "panic: stored minter should not have been nil"
• make test-sim-nondeterminism-state-listening-trace -> "panic: stored minter should not have been nil"
• make test-sim-nondeterminism-state-listening-kafka -> "panic: stored minter should not have been nil"

Once fixed, the .github/workflows/sims.yml file should be updated too, so that those tests run.

After some more digging, I found that the following sims are broken:

• test-sim-after-import: "panic: expected validator, not found"
• test-sim-nondeterminism-state-listening-file: "panic: stored minter should not have been nil"
• test-sim-nondeterminism-state-listening-trace: "panic: stored minter should not have been nil"
• test-sim-nondeterminism-state-listening-kafka: "panic: stored minter should not have been nil"
  I've updated the issue to reflect this.

No longer an issue. the state listening ones were removed and the after-import sim has been fixed.
