GraphQL and Spring Security @PreAuthorize for Spring Boot webflux project

[stasbit]

Hello team,

I was recently asked to add Security support for kotlin Spring boot webflux service. After add certain spring security dependencies, I observer that test endpoint retruns Access Denied exception.

How to reproduce

1. Test service - https://github.com/stasbit/webflux-security-demo-service
2. Create test JWT token(http://jwtbuilder.jamiekurtz.com) here and put it to cookie "access_token". Add Claim Type "Roles" with values 'USER, MANAGER'
3. Send Query to getAllBooks
