Root Cause

When morphing the Process into a Collaboration, the ID get's unclaimed.

bpmn-js/lib/features/modeling/behavior/UnclaimIdBehavior.js

Line 50 in fe11c2e

moddle.ids.unclaim(rootElementBo.id);

With camunda/camunda-modeler#1410, we keep the IDs when copying Elements, so we create the process with the same ID again.

Solution Sketch
Determine if it makes sense to unclaim IDs when the root changes but nothing is deleted and either:

• Remove the code that unclaims the ID
• Ensure the ID is re-claimed once the new participant with a processRefis created
