cant upgrade from laravel 5.1.46 to to 5.2 - laravel

Question

I'm struggling to update an 2015 application from laravel 5.1.46(LTS) to 5.2,
I've done composer require "laravelcollective/html:5.8.0" --with-all-dependencies
and it fails.
I'm doing this because I see the error Call to undefined method Illuminate\Foundation\Application::bindShared() in some step when following https://laravel.com/docs/5.2/upgrade#upgrade-5.2.0 and cant continue unless I do a git reset --hard, I'm clueless.
here is my composer.json
