test(dht): Equality check in Mock-Layer1-Layer0.test.ts (#3129)

Use `toIncludeSameMembers()` instead of `toContainValues()`.

The `toIncludeSameMembers()` is better check as both arrays should match
exactly. In a previous line already check that there are equal items in
the list, i.e. the lists won't contain additional values (which would be
tolerated by `toContainValues()` but not by `toIncludeSameMembers()` )
```ts
expect(layer1Node1.getNeighborCount()).toEqual(layer0Node1.getNeighborCount())
```

This should resolve the test failure in
#3127.
