Implement a test to ensure DB tables are created and queried using all uppercase characters

[mboskamp]

Acceptance Criteria (Required on creation)

We have tests in all places where there is interaction with DB tables to ensure table names are always upper-case.

Background: DBs can be configured using a case-sensitive collation. We need to ensure that this won't break functionality in Camunda Platform 7.

Hints

Known places are:

• CE engine
• CE webapps
• EE webapps

There are tests for column names already:
