Orm Diagram breaks when there are no project associated with a console configuration

EXECUTE: Create a console configuration that does not point to a project
EXECUTE: Right click an entity in Console View and choose show mapping diagram
ASSERT: No Exceptions and diagram shown

Now you get:
java.lang.NullPointerException

Because the diagram assumes there is a project associated with the launch configuration. This is a wrong assumption
plus it potentially mixes up settings for multiple console configurations. If something needs to be saved it should be done
in context of the launchconfiguration location/name.

i.e. a workspace preference keyed by launch config name or by saving settings where the launch configuration is stored.
