* test: saving multiple versions with unique fields
* fix: saving multiple versions with unique fields
Version schemas were getting produced with uniqueness constraints which
caused updates to likely fail because each successive version would
potentially reuse unchanged unique key-values (particularly ident keys
like slug) from previous versions.
This was due to `mongoose.buildSchema` not respecting buildSchemaOptions.disableUnique.
This regression was introduced with the fix at commit c175476e.
