Fix or remove settings equality operators

[confluence]

The equality operators for ProgramSettings use a GetTuple function which hasn't been updated to include new fields (so they no longer actually check for equality). The equality operator is only used in the empty arguments test of the settings class. Adding more of the fields causes the test to fail, because e.g. event_thread_count is set to a new value dynamically when CARTA is run with no parameters.

Either the test needs to be revised to work with an operator which correctly checks for equality, or the operator should be removed from the main codebase and replaced with a test function which is more specifically tailored to the test.

I will commit a proof of concept updated equality operator to a branch.

A proof-of-concept solution for updating the operators is in the branch 1001_settings_equality_operators.

• This solution does not check additional fields like no_user_config, etc., which should possibly also be added for completeness.
• There's a typo in the test name which this branch fixes.

Given that the operator is only used in this test, I think it would probably be a better idea to remove the operator and rewrite the test.

I would suggest removing the operator entirely and rewriting the test to add some kind of test-specific comparison function.
