Note: this is about #3647 but won't probably make it reach 90%

thanks for the test! maybe there is a better place for this test btw? maybe tests/abi_types/test_invalid_abi_types.py

moved the logic for 2-dimensionnal parametrization inside the test, changed variants to a tuple, and move the file to the new location !
