Prevents server adapter editor to switch connections

steps:

1. ASSERT: make sure that you have a connection to an OpenShift instance
2. ASSERT: make sure that you have an application running (ex. nodejs)
3. ASSERT: make sure that you have a server adapter for it
4. EXEC: delete the connection
5. EXEC: restart Eclipse
6. ASSERT: the editor has an empty Connection combo (no Connection selected).
   
7. EXEC: if you have 2 connections (ex. connection to OpenShift online at https://console.starter-us-east-2.openshift.com/):
   try to select the other connection in the connection combo:
   Here's the 1nd flaw: the connection combo is not selectable. You CANNOT choose the OTHER connection.
   Then there's a 2nd flaw: the project is NOT filled out
   
8. EXEC: hit "New" on the right of the "Connection:"-combo
9. EXEC. create a new connection

Result:
The new connection shows up in the OpenShift Explorer but is NOT set in the adapter editor, the connection combo stays empty
