Explorer: connection is not refreshed if you modify it

1. ASSERT: have a running CDK and a connection for it in OpenShift Explorer
2. ASSERT: have your connection unfolded showing at least 1 project and at least 1 service
3. EXEC: minishift delete && minishift setup-cdk && minishift start
4. ASSERT: cdk starts up and picks a new ip (ex. 192.168.64.20 -> 192.168.64.21)
5. EXEC: in Explorer: pick "Edit Connection" in the context menu
6. ASSERT: connection wizard shows up
7. EXEC: update the server url to point to the new IP address of the cdk
8. EXEC: hit "Finish"

Result:
The explorer still shows the old project and resources. You have to manually hit "Refresh" for it to replace the initially present project and it's children by the new project (which is by default "My Project", the default project)
