Queries / tests that required changes:
* The CleartextLogging and MissingErrorCheck queries are updated because they assumed def-use flow
* The CommandInjection query works around the shortcomings of use-use flow by essentially reintroducing def-use flow when it applies a sanitizer
* The OpenUrlRedirect query currently just accepts its fate; the tests are updated to avoid excess sanitization while the query comments on the problem. We should choose this approach or the CommandInjection one.
