Add tests for set-implementation template

[ajsutton]

The fp-recovery set implementation task could use a test to ensure it is always ready to use.

normally what we do for testing in-progress tasks is just simulate them in CI and ensure they don't revert (either the sim itself, or failed solidity checks). So if we do want to test these, I'd suggest something similar, where we do have the extra preceding step of generating the task from the template in CI

for example we always run the security council rehearsal tasks in CI here which ave a similar "setup from template" step
