TIF: Fix a bug of incorrect watch history

When the user keeps watching one channel without tuning to the other
channel, the user can watch many programs. In this case as many watch
history records as the number of programs the user watched should be
inserted in watched_programs table.
But there is a bug now that only one record is logged for all the
programs and this CL fixes the bug and makes the watch history
logging work correctly for this case.
In addition, package information should be added to the content value
because it should be not null in programs table.
