Deploy Docker Wizard: always prompts to create a new connection, does not preselect most recently used connection

steps:

1. ASSERT: make sure that you have at least 1 connection to a OpenShift server defined
2. ASSERT: do some operations involving your existing connection (ex. open children for it in OpenShift Explorer)
3. EXEC: in "Docker Explorer": select an image and pick in the context menu "Deploy to OpenShift..."

Result:
You get prompted to create a <New Connection>

If you unfold the "Connection" combo box to list all connections you discover your connection and can pick it instead of the suggested <New Connection>

Expected result:
The connection page shows up with the most recently connection preselected.
