analytics: Remove test for no longer supported behavior.

In a previous design, there was no FillState table, and one could run any
CountStat at any time. This is no longer supported.

This test was making sure that if one ran a CountStat at a certain hour, and
then ran it at a previous hour, the old rows would still be there.
