Redundant updates of collection used as an array column

[Nawrok]

The library supports collections supported as an array column. However, a problem occurs when updating an already existing entity, for which unnecessary statements are executed. If the collection of elements held as array column type has not changed, SQL statements are executed anyway. The problem is in the needsUpdate() method in the SaveProcessor class. The compared reference between persisted and actual collections is never satisfied. Object.deepEquals() alone would be sufficient.
