[incubator-kie-issues-1131] test migration from V7 to code generation-34

[Abhitocode]

Below are the tests with issues, commented the same for each test.

1. IntermediateEventTest

• For tests,
  testIntermediateCatchEventCondition, testIntermediateCatchEventConditionFilterByProcessInstance, testConditionalBoundaryEventOnTaskComplete, testConditionalBoundaryEventInterrupting

for the tests with getKieSession,
How to add the person variable to the session? The model doesnot have the person field. Even after the person variable is added in the bpmn file, the test fails with a NPE,

When i try to complete workItem Im getting below error:

Caused by: java.lang.NullPointerException: Cannot invoke
"org.jbpm.process.instance.impl.AssignmentAction.execute(java.util.function.Function, java.util.function.Function, org.jbpm.process.instance.impl.AssignmentProducer)" because "action" is null at org.jbpm.workflow.core.impl.NodeIoHelper.handleAssignment(NodeIoHelper.java:113)
exception is this, org.jbpm.workflow.instance.WorkflowRuntimeException: [DataOutputAssociations:fa7cbf6e-fe07-408b-abcd-92ea30bed450 - Task:[uuid=_2]] -- java.lang.RuntimeException: Unable to execute Assignment

2. StartEventTest

• For *MultileStartEvent tests

we get below error:
org.kie.kogito.process.validation.ValidationException: A process cannot have more than one start node!

BPMN process definition includes multiple start events, but I if im not wrong Kogito seems to only support a single start node per process. Could you please clarify if there's a way to handle multiple start events within a single Kogito process definition or suggest an alternative approach ?

guidance on above would be helpful.

Closes apache/incubator-kie-issues#1131.

the test here cannot be migrated due to kie session not working on kogito.

this requires a prior fix to condition activation.
