laravel update from 5.1 to 5.2 composer update error

I am trying to update laravel from 5.1 to 5.2 . I followed the instruction as according to update doc but I am getting this error when running composer udpate:

Error Output: PHP Fatal error: Call to undefined method Illuminate\Foundation\Application::bindShared() in /my_app/vendor/illuminate/html/HtmlSe rviceProvider.php on line 36

I've looked up this issue and saw that people were getting this issue when updating to version 5.1 and saw that the method bindShared has been replaced with singleton(), but I don't want to mess with vendor files. Here is my config/app.php providers and aliases arrays:

'providers' => [

    /*

     */

any idea what I should do to fix this? I started with a 5.1 version install of laravel.
