Remove `@Persistent` from entity-scan include filters.

We now only scan for entities annotated with `@Document` to avoid inclusion of non-MongoDB entities. Previously, types annotated (or meta-annotated) with `@Persistent` were included as MongoDB entity which could lead to mapping rule violations.

Closes #3592
