Show in browser: missing project/server that we're listing the routes of

how to reproduce:

1. ASSERT: make sure that you have a project with several routes on a v3 OpenShift server
2. ASSERT: make sure that you have a connetion in explorer to this server
3. EXEC: in Explorer: unfold Routes and pick "Show in->Web Browser"

Result:

A dialog requiring to select the route that you want to open up in the browser pops up. The dialog wont tell you what server, project the routes are listed for.
