Improve the concurrent refresh test

Browse Source 
This change moves the invalidation threshold in the setup phase of the
concurrent refresh test for continuous aggregates in order to generate
invalidations. Without any invalidations, the invalidation logs are
never really processed and thus not subjected to concurrency.
