Could you please raise a PR for this fix? I'll do a quick rollout if all check passed.

--> #1164
I also ran the tests from my project against the version with the bugfix and everything looks good. Not sure if there are any edgecases you can think of that are also worth testing.

It seems like #1117 breaks support for databases created with
4.3.0- at least when working with repositories. The following exception is thrown:and the database is rolled back to an earlier version. In my case this was luckily caught in a test as it seems to result in a wipe of the collection in the database.
