[incubator-kie-issues-1131] test migration from V7 to code generation-35

[Abhitocode]

Migrated testErrorBetweenProcessesProcess within ActivityTest.java based on the changes suggested as below,

Application app = ProcessTestHelper.newApplication();
        ProcessTestHelper.registerProcessEventListener(app, new DefaultKogitoProcessEventListener() {
            @Override
            public void afterProcessCompleted(ProcessCompletedEvent event) {
                if ("ErrorsBetweenSubProcess".equals(event.getProcessInstance().getProcessId())) {
                    assertThat(event.getProcessInstance().getState()).isEqualTo(ProcessInstance.STATE_ABORTED);
                }
            }
        });
        ErrorsBetweenSubProcessProcess.newProcess(app);
        org.kie.kogito.process.Process<ErrorsBetweenProcessModel> process = ErrorsBetweenProcessProcess.newProcess(app);
        ErrorsBetweenProcessModel model = process.createModel();
        model.setTipoEvento("error");
        model.setPasoVariable(3);
        ProcessInstance<ErrorsBetweenProcessModel> processInstance = process.createInstance(model);
        processInstance.start();
        assertThat(processInstance.status()).isEqualTo(ProcessInstance.STATE_COMPLETED);

        Assertions.assertEquals("error desde Subproceso", processInstance.variables().getEvent());
