Add all state income tax variables to test_microsim.py

https://github.com/PolicyEngine/policyengine-us/blob/master/policyengine_us/tests/microsimulation/test_microsim.py currently only checks `household_net_income`. While we don't expect accurate results from state income taxes not yet hooked up to the net income tree, they shouldn't break like they did in https://github.com/PolicyEngine/policyengine-us/issues/3971. If we add all state income tax variables to this microsim check, including those in progress, we should at least catch broadcast errors.
