[BUG]: Model::getMessages does not allow filtering messages by array of fields

[SliceOfLife]

Describe the bug
We can validate Model by several fields at once, for example, by Uniqueness validator. But if the filter is producing an error, we can't get only this message by calling Model::getMessages(['field1', 'field2']) because internal implementation allows only strings as messages filter:

    public function getMessages(var filter = null) -> <MessageInterface[]>
    {
        var message;
        array filtered;

        if typeof filter === "string" && !empty filter {
            let filtered = [];

            for message in this->errorMessages {
                if message->getField() == filter {
                    let filtered[] = message;
                }
            }

            return filtered;
        }

        return this->errorMessages;
    }

To Reproduce
Steps to reproduce the behavior:

$model->getMessages(['login', 'loginType']); // Returns all Model messages, not just the ones I need

Provide minimal script to reproduce the issue

class User extends Model
{
	public function validation(): bool
	{
		$validator = new Validation();
		$validator->rules(['login', 'loginType'], [
			new Validation\Validator\Uniqueness([
				'model' => $this,
				'message' => 'Login already in use',
			]),
		]);

		return $this->validate($validator);
	}
}

Expected behavior
I expect to get messages related to the specified pair of fields.
