Connection wizard: connecting to a server configured for basic auth with Oauth scheme provides no indication

1. ASSERT: make sure you have an openshift server configured to basic auth (only, no oauth)
2. EXEC: Launch connection wizard, create a new connection, use url of this server in "Server Url" and server type to "OpenShift v3".
3. EXEC: in "Authentication" details pane hit the "retrieve link"
   Result:
   The progress bar shows up for a short time and disappears right afterwards. There's no info in the wizard that tells you why retrieval didnt show up the browser.

Expected result:
There's an error that tells you that the local server doesnt support oauth and that you should use basic auth.

It previously worked until we had to alter the 'retrieve' browser to utilize external. This may be resolved if we can re-introduce the original browser dialog
