Symptom:
Navigation icon ">" should be disable after group removal in LCC.

Conditions:
Steps :
1. Navigate to Operate --> LCC
2.Verify in Device Group Selector, icon ">" is not displaying in front of "User Defined Group", as no group is created and so navigation should not happen.
3. Create a group by clicking on 'Create New' group button , group will be created.
4. Now we can see the icon ">" in front of user defined group, and we can navigate inside it to the group which we created in step 3.
5. Delete the group created in step 3
6. Since the group is deleted then also, we are able to see the navigation icon ">" in front of the user defined group, which should not happen.
7. As the group is deleted this navigation icon ">" should get disable automatically after deletion of a created group, if no group are present in user defined group.
