Patch test databases for release 97, part 2 [release/97]

Created by: mkszuba

Description

This PR patches test databases on the branch release/97 so that they are fully up to date with the schema version 97.

Use case

The previous test-database update missed some patches for the core and variation schemas, which is why Travis jobs keep failing these days.

Benefits

Tests will no longer fail due to schema incompatibilities.

Possible Drawbacks

This should have been taken care of before the branching.

Testing

Have you added/modified unit tests to test the changes?

No

If so, do the tests pass/fail?

N/A

Have you run the entire test suite and no regression was detected?

Run the whole test suite, no errors.
