Show in Browser: route chooser should allow to user to choose route permanently

steps to reproduce:

1. ASSERT: have an apps with service and route running on OpenShift. Have it imported to your workspace
2. ASSERT: you need at least a 2nd route in the same project (ex. by having a 2nd app in the same project)
3. EXEC: launch New OpenShift 3 Server Adapter wizard
4. ASSERT: make sure that you have Prompt for route when multiple routes available to show in browser checked (no route permanently selected)
5. EXEC: create the adapter by picking service, local project etc.
6. EXEC: in the context menu of your new server adapter: pick Show In > Web Browser
7. ASSERT: Route chooser shows up (since there are several routes available)

Result:
There's no way to permanently choose a route. The route chooser will always show up (as long as I have several routes in the same project)
