0002542: Crash whilst generating web pages from command line

Throwing Report Error if center person is not in database. Added catching of Report Error to CommandLineReport
if using GUI it is not possible to cause this, as you have to select a person that is in the DB. However on the command line you can specify any PID and even no person with that pid exists an error was thrown.
