More reliable test setup in integration-tests/hibernate-orm-tenancy/d…

…atasource

The previous config was relying on FlyWay on a default datasource to create other databases
which named datasources pointed at.

Which works well, until a named datasource gets initialized before the default datasource;
then named datasource initialization fails because the corresponding database doesn't exist yet.

This happened on my local laptop, I don't know why it didn't happen on CI.
