Folder should stay present in Configuration view if objects cannot be removed from Controller

Current Behaviour:

• When we remove a folder from the configuration view consisting of a workflow, file order source, and a notice board. The deployed workflow which is present in the Workflow View is not removed.
  i.e. The folder is getting removed even though the objects from this folder are not getting removed from the controller.

Steps to reproduce:

• Deploy a folder containing a workflow w1, a notice board n1 and a file order source s1.Then remove the folder from the Configuration view.
• Then change to a different tab or view, then back to Configuration view still, the folder is not present.
• Also in the Workflow view, the deployed workflow is still present, and will be executed when triggered by the file order source.

Desired Behaviour:

• The folder should not be removed from the Configuration view if its related objects have not been deleted from the Controller.
