Reimplement wrongly implemented test_change_tools_after_init

[albertvillanova]

Reimplement wrongly implemented test_change_tools_after_init to validate intended behavior.

The 2 test_change_tools_after_init tests were identified as wrongly implemented: they do not correctly validate the intended functionality. These tests have been temporarily disabled via @pytest.mark.skip in

• Temporarily skip wrongly implemented tests #1571

This issue tracks the work needed to properly reimplement these tests to ensure they accurately validate the intended behavior.
