Voter with $user as argument

[gulien]

GraphQLite seems to have an issue when you uses $user as argument:

    /**
     * @Query
     * @Logged
     * @Security("is_granted('GET_USER', user)")
     */
    public function user(User $user): User
    {
        // ...
    }

Here the subject of the voter, user, is always equals to the authenticated user.

Workaround: rename the argument $user.
