Revert H2 Upgrade

The latest version of H2 isn't compatible with IntelliJ's database explorer, and offered no immediate value in upgrading. Initially it was presumed to have been the fix to some syntax errors, but running H2 in sql mode resolves all of those even on the older version of H2 so we are reverting
