Java: Adapt to changes in FlowSummaryImpl

Missing manual models were added using the following code added to `FlowSummaryImpl.qll`:

```ql
    private predicate testsummaryElement(
      Input::SummarizedCallableBase c, string namespace, string type, boolean subtypes, string name,
      string signature, string ext, string originalInput, string originalOutput, string kind,
      string provenance, string model, boolean isExact
    ) {
      exists(string input, string output, Callable baseCallable |
        summaryModel(namespace, type, subtypes, name, signature, ext, originalInput, originalOutput,
          kind, provenance, model) and
        baseCallable = interpretElement(namespace, type, subtypes, name, signature, ext, isExact) and
        (
          c.asCallable() = baseCallable and input = originalInput and output = originalOutput
          or
          correspondingKotlinParameterDefaultsArgSpec(baseCallable, c.asCallable(), originalInput,
            input) and
          correspondingKotlinParameterDefaultsArgSpec(baseCallable, c.asCallable(), originalOutput,
            output)
        )
      )
    }

    private predicate testsummaryElement2(
      string namespace, string type, boolean subtypes, string name, string signature, string ext,
      string originalInput, string originalOutput, string kind, string provenance, string model,
      string namespace2, string type2
    ) {
      exists(Input::SummarizedCallableBase c |
        testsummaryElement(c, namespace2, type2, _, _, _, ext, originalInput, originalOutput, kind,
          provenance, model, false) and
        testsummaryElement(c, namespace, type, subtypes, name, _, _, _, _, _, provenance, _, true) and
        signature = paramsString(c.asCallable()) and
        not testsummaryElement(c, _, _, _, _, _, _, originalInput, originalOutput, kind, provenance,
          _, true)
      )
    }

    private string getAMissingManualModel(string namespace2, string type2) {
      exists(
        string namespace, string type, boolean subtypes, string name, string signature, string ext,
        string originalInput, string originalOutput, string kind, string provenance, string model
      |
        testsummaryElement2(namespace, type, subtypes, name, signature, ext, originalInput,
          originalOutput, kind, provenance, model, namespace2, type2) and
        result =
          "- [\"" + namespace + "\", \"" + type + "\", True, \"" + name + "\", \"" + signature +
            "\", \"\", \"" + originalInput + "\", \"" + originalOutput + "\", \"" + kind + "\", \"" +
            provenance + "\"]"
      )
    }
```
