Updated MySQL JDBC driver to 8.0.19. The 8.0.20 was also tested but there seems to be an issue with Date parameters in some queries: ​https://bugs.mysql.com/bug.php?id=99713

I have also changed the default configuration to use MySQL 8.

There was an issue with the TestChangeHistory.test_list_by_user() that sometimes worked and sometimes failed. The most likely reason is the filter on the current time which could be affected by rounding milliseconds up/down, so the timestamp used for filtering was modified by -1 second.
