Incorrect fix for multi-line array

[andrewnicols]

        $fields['maildigest'] = ['type' => PARAM_INT, 'null' => NULL_NOT_ALLOWED,
                'default' => $CFG->defaultpreference_maildigest, ];

Should be:

        $fields['maildigest'] = [
            'type' => PARAM_INT,
            'null' => NULL_NOT_ALLOWED,
            'default' => $CFG->defaultpreference_maildigest,
        ];

Is that the NormalizedArrays.Arrays.CommaAfterLastsniff?

If so, yeah, that one is imperfect, recently we were able to get accepted some new error codes, in order to allow missing trailing commas when the closer (]) is in the same line (we allow that), but I imagine that, maybe, the fixer does not consider that. Tricky one as far as it's not ours...
