If value is not a string - make it a string. This is really hacky - but its due to the lack of type metadata on readModels!
Introducing a isCommandRoot() property that aggregatedCommands and hasChanges honor.

When reaching a region that has this, it acts as a root and will not include it and
its children in the recursive aggregation!

Thanks to Børge Nordli for this!
