[P1] Expected list ignores shared selector emissions

This test merges four selectors, but the first selector (interval(0L, 100L)…withLatestFrom(sharedFlow).takeUntil(sharedFlow.filter { it == 3 })) emits at least (1, "shared") and (2, "shared") before the shared flow reaches 3. Because the assertion only includes the odd, even, and string pairs, the collected result will contain additional elements and the test will fail whenever it is run. Either include the shared selector’s outputs in the expected list or modify that selector so it deliberately produces no values.
