chore: upgrade to github.com/upper/db/v4 (#705)

* Upgrade to github.com/upper/db/v4

* fix(oonitest): repair imports after merge

Oops, okay, it seems the merge did not preserve all the import
changes, so let's ensure we use the right imports here!

* cleanup(go.mod): don't refer to upper.io/db/v3

These lines didn't disappear previously because the merge commit
failed to remove all references to upper.io/db/v3.
