Fix retrieval of null job parameters of type long/double

Browse Source 
Before this commit, a null job parameter of type long
or double was retrieved as 0L or 0.0. This caused
JobOperator.restart to create a new job instance
instead of restarting the previous failed execution.

This commit fixes how null job parameters of type
long or double are retrieved from the database to
correctly restart the same job instance.
