Add select e2e test to demo issue when select within include

[ranmocy]

First thanks for the awesome project!

I found an issue in my production code so here is the e2e test to reproduce it.
When I select only some fields in a nested table, and the select clause is within another include clause, this bug happens. It doesn't automatically filter the deleted nested items any more. If I explicit select the deleted field, then it works as expected.

If you run this test, you will see findFirst with include and select is failed, but findFirst with include and select deleted field is passed.

Failed test:

 FAIL  test/e2e/select.test.ts
  ● select › findFirst › with nested select › findFirst with include and select

    expect(received).toHaveLength(expected)

    Expected length: 1
    Received length: 2
    Received array:  [{"id": 1}, {"id": 2}]

      224 |         expect(foundUser!.posts).toHaveLength(1);
      225 |         // TODO: this should be 1
    > 226 |         expect(foundUser!.posts[0].comments).toHaveLength(1);
          |                                              ^
      227 |         expect(foundUser!.posts[0].comments[0].id).toBe(comment1.id);
      228 |       });

I suspect it's due to this part of the code, as it skips the recursion:

prisma-extension-soft-delete/src/lib/helpers/createParams.ts

Lines 416 to 420 in b64da3e

	export const createSelectParams: CreateParams = (config, params) => {
	// selects in includes are handled by createIncludeParams
	if (params.scope?.parentParams.operation === "include") {
	return { params };
	}

But I'm not sure yet what's the right fix, or if there are any other pitfalls ahead.

Thank you for raising this, and for the e2e test!

I'm not sure right now what the fix is, but I will get to it as soon as I can 😄

I'm glad you are finding the library helpful, please don't hesitate to raise any other issues you find or any ideas you have 🙏
