how to reproduce:

1. ASSERT: make sure that you have at least 1 connection to a v3 server defined (showing up in OpenShift Explorer)
2. EXEC: launch v3 OpenShift server adapter wizard via File > New > Server > OpenShift 3
3. ASSERT: connection dialog shows up as 1st wizard page

Result:
<New Connection> is preselected even though I have 1 v3 connection:

Expected Result:
The last v3 connection that I used should be preselected (if it exists)
