Artem Bilan 973276fc0a Fix count and update in MongoDb stores ...

* The `into()` query can't infer the type for entity if we provide `Object.class`
* The `updateFirst()` does not support sort queries any more - replace with `findAndModify()`
* Add `getMessageGroupCount()` into tests

**Cherry-pick to 5.3.x & 5.2.x**
