Pass HttpContextAccessor httpContextAccessor to manager

[EvilLord666]

All manager classes should receive IHttpContextAccessor that could be used as follows:

public static class UserService
    {
        public static Guid GetCurrentUserId(IHttpContextAccessor accessor)
        {
            Claim claim = accessor.HttpContext.User.Claims.FirstOrDefault(c => c.Type == "id");
            if (claim == null)
            {
                string msg = "Authorization server does not contains \"id\" property in UserInfo, ensure that you properly configured your UserProperty Mapper";
                throw new InvalidOperationException(msg);
            }

            return Guid.Parse(claim.Value);
        }
    }
