Remove unused notification in print code to simplify before refactoring.

Removed the PRINTED_DOCUMENT_UPDATED notification and move the debug output from PrintJobManager to PrintedDocument.
Also made the --debug-print startup parameter only active in non-official builds.

BUG=none
TEST=Should have no functional affect.
