Compatibility with php 7.2

[Simutin32]

PHP Compile Error 'yii\base\ErrorException' with message 'Cannot use yii\base\Object as Object because 'Object' is a special class name'

in ../vendor/frostealth/yii2-aws-s3/src/HandlerResolver.php:9

Stack trace:
#0 [internal function]: yii\base\ErrorHandler->handleFatalError()
#1 {main}

As sujesting yii2 team in upgrade note:
"For extensions that have classes extending from yii\base\Object, to be compatible with PHP 7.2, you need to require "yiisoft/yii2": "~2.0.13" in composer.json and change affected classes to extend from yii\base\BaseObject instead. It is not possible to allow Yii versions <2.0.13 and be compatible with PHP 7.2 or higher."
