Stopping a resource works only once

[vadimeisenbergibm]

When you perform manual healing on a resource with Start transition, the first healing (Stop/Start) succeeds and the resource is deleted/created again. Subsequent healing (Stop/Start) fails due to a Duplicate key error. Moreover, Uninstall also fails - the resource cannot be stopped anymore.

See execution history:

Steps to reproduce the bug:

1. Generate.an empty resource with lmctl project create
2. Add the Start transition with the same object as in Create (a ConfigMap) to Lifecycle/kubernetes/kegd.yaml
3. Add the Start and the Stop transition to Definitions/lm/resource.yaml.
4. Create an assembly for that resource.
5. Create an assembly instance
6. Heal the resource - it should succeed. Verify that the ConfigMap was indeed deleted and created anew.
7. Heal the resource - it will fail.
