It allows to have 2 "different" connections for one connection - 2 items in OpenShift Explorer view for same thing.

Steps to reproduce:
1. EXEC: Open OpenShift explorer view
2. EXEC: Create connection to default OpenShift server with some credentials (checkbox for default server MUST BE checked)
3. ASSERT: Have connection in view with label "user server (default)"
4. EXEC: Open new connection shell (to create new connection)
5. EXEC: Uncheck checkbox for default server, but leave the same name and provide same credentials as in step 2.
6. EXEC: Confirm connection creation
7. ASSERT: There are now 2 "different" connections for same connection in OpenShift explorer view (e.g. "mlabuda@redhat.com openshift.redhat.com (default)" and "mlabuda@redhat.com openshift.redhat.com").

Probably connections are distinguished by labels, I guess.
