Description

The php_unit_method_casing is renaming private methods.

Unless this rule is going to refactor the calls to the methods it renames, it should only apply to public methods (actual test cases in PHPUnit). Any other method visibility should not have it's name changed.

Steps To Reproduce

• Create a private method using camelCase in your test cases
• Run pint
