Prompt the user to select a project

When trying to run "Start Dev", "Manually Start Dev",
"Create" (to create resources from a YAML file),
or "Delete" (to delete resources from a YAML file),
if the current project doesn't exist,
display a notification initicating that a project needs to be selected
or created,
with a button that opens the wizard to do this.

Fixes redhat-developer#2581
