Camunda-modeler: Direct Editing Not Completed on Drill Down

[philippfromme]

__Describe the Bug__

When navigating through drill down active direct editing is not completed.

There is a fix for this issue: https://github.com/camunda/camunda-modeler/tree/develop/client/src/app/tabs/bpmn/modeler/features/complete-direct-editing

This fix also must be applied to drilling down.

1. Start direct editing
2. Drill down
3. Go back to DRD
4. Direct editing still active

__Expected Behavior__

Drilling down completes direct editing.

__Environment__

• Camunda Modeler Version: 4.1.0
