apt-dater -rn gets stuck in a loop

[JasonCormie]

When doing a report without networking for a number of hosts, apt-dater gets stuck in a loop.

I have done some investigation.
in report.c/ ctrlReport

the section that outputs the xml relies on torefresh == 0, but as the hosts don't get refreshed, if it started as a non zero value, it will never reach 0.
