Looks like we have started to fail much often
since upgrade to the `Derby-10.14.1.0`:
cb0d43db6b
That is also related to this https://jira.spring.io/browse/INT-4445
* Remove all the `drop` mentioning for Derby scripts -
it just doesn't support `IF EXISTS`.
More over we don't need to worry about drops since each test now starts
its own fresh embedded DB
**Cherry-pick to 5.0.x**
