The regression tests of extended statistics were taking a fair amount of time, due to using fairly large data sets with a couple thousand rows. So far this was fine, but with tests for statistics on expressions the duration would get a bit excessive. So reduce the size of some of the tests that will be used to test expressions, to keep the duration under control. Done in a separate commit before adding the statistics on expressions, to make it clear which estimates are expected to change.
