Patch the variation test database to version 98 [release/98]
Created by: mkszuba
I forgot that patch_test_databases can only handle single-version bumps so with the test databases having only fully been sinced with 97 on the relevant release branch, the variation schema ended up remaining at 96 on master even when all other DBs got bumped to 98. Manually apply variation schema patches to bring that test DB up to date.
