With CAM-1689 it is possible to create a custom incident, for example:

runtimeService.createIncident("foo", ...);

In that the a registered custom incident handler name foo is not called.

AT:

• when a custom incident is created and a custom incident handler for the given type exists, then the custom incident handler should be invoked to create the incident
• if there does not exist a custom incident handler for the given type, then an incident is created (without calling any custom incident handler)
• the same behavior should also be applied in case of resolving a custom incident
