Description

If we have a mapping rule which places the application to the %specified queue, then application submissions without specified queues (default) will get placed to default. 

The expected behaviour would be to fail the specified placement when no queue was specified, and move on or reject based on the fallback action of the rule. 

Also it is impossible to differentiate between explicitly specified 'default' and when the user does not specify any actual queue, so these will be handled the same.
