Fix MongoDB throwing error when perPage is string

Hello, we're using MongoDB in our Laravel project and it seems to require strictly integer type when passing the limit for pagination.
Whenever you attempt to change Per Page in frontend it will replace `$perPage` to a string type and when `render` function calls `paginate` it will throw error.

This pull request fixes it, but not sure if it is the right place where to type cast.
