Runtime Bundle: Incorrect status for process instance when starting c…

…reated process (Activiti#3463)

* Reproduce AAE-3508 using an Integration Test to debug further

* Update Execution.xml for update command to set startTime as HistoricProcessInstance.xml does

* Add a unit test for activiti engine and adjust integration test for duplicate assert statement
