Checklist

• [ ] Appropriate tests were added
• [x] Any code changes were done in a way that does not break public API
• [ ] All documentation related to code changes were updated

Additional context

It seems that the methods MOI.eval_constraint_jacobian_transpose_product and MOI.eval_constraint_jacobian_product were incorrectly both evaluating the products and erroring when the evaluator possessed cons_vjp or cons_jvp functions.

Add any other context about the problem here.

Can you add a test which catches this?

@aml5600 can you add the test, happy to merge it right away once that's added

@Vaibhavdixit02 sorry for the delay, please let me know if the tests are sufficient. They failed before, passed after the changes.
