Revert "erp5.mariadb: Create no test database by default."

This reverts commit 37a0e975.

It was too early to change this default value, code requesting test
instance is not ready for this yet, which in turn prevents latest SR
improvements from being tested. Break the cycle by creating test databases
again. This code will go away again in the future.
