Fix/update dependencies infer paginate params

[fratzinger]

Problem:

I use the [key: string]: any hack for Params, as suggested in the migration guide:

declare module "@feathersjs/feathers" {
  interface Params {
    [key: string]: any;
  }
}

see: https://feathersjs.com/guides/migrating.html#typed-params-and-query

When doing this, the find params can not be inferred correctly and the function overloads do not work. By using conditional types the ReturnResult is correct.
