* [ACTIVITI-3602] Support for BPMN message events

* [ACTIVITI-3602] Tests updated

* [ACTIVITI-3602] Replace set with list of messageEvents

As message events use a specific class (ActivitiMessageEvent) instead of generic ActivitiEntityEvent it's possible to simplify the converter logic

* [ACTIVITI-3602] Unit tests added for message events converters

* Remove unnecessary initMocks

No field is annotated with @Mock or @InjectMocks
