Incorrect Translation or Incorrect Expected Output for IncludedInNullLeft and IncludesNullRight

The CqlListOperatorsTest.IncludedIn.IncludedInNullLeft test specifies the following CQL:

null included in {2}

and the expected output null. The CQL Translator, however, translates it as the point/list overload, exporting it as an In operation that therefore should result in false.

The CqlListOperatorsTest.Includes.IncludesNullRight test specifies the following CQL:

{'s', 'a', 'm'} includes null

and the expected result null. The CQL Translator, however, translates it as the list/point overload, exporting it as a Contains operation that therefore should result in false.

That being the case, test engines that execute the CQL based on the CQL Translator's output will fail these tests. I'm not sure which is the best way to resolve this, but it seems there are three choices:

1. Update the tests to cast the nulls to lists so the translator uses the list/list overloads.
2. Update the tests to expect false so they are in alignment with the translator's approach.
3. Update the translator to treat these as interval/interval overloads so it maintains the IncludedIn / Includes operations.

Start with CqlListOperatorsTest.xml at the IncludedInNullLeft lines 422-425 and IncludesNullRight lines 379-382, then inspect how the CQL Translator handles these overloads. Determine which interpretation matches the intended CQL behavior, update the tests or translator accordingly, and verify that the affected test engines no longer disagree with the expected results.
