"fix-states -a" in console prints out a lot of notice warnings

[karmrt]

Issue present in 3.0.0-alpha4. Happens when running vendor/bin/oxid fix:states -a. The diff function gets multidimensional arrays like this to compare:

[
    'vendor/module' =>
        [
            'something' => 'SomeNamespace\\SomeClass',
        ],
];

Then the function array_diff_assoc basically takes ['something' => 'SomeNamespace\\SomeClass'] and casts it to a string according to:
https://www.php.net/manual/en/function.array-diff-assoc.php#refsect1-function.array-diff-assoc-notes

Notice: Array to string conversion in /var/www/oxideshop/vendor/oxid-community/moduleinternals/Core/ModuleStateFixer.php on line 373
