Export/Import of topic

[dr-consit]

When exporting a topic that has a session with a filter on SessionId all other filter properties are exported as empty.
When trying to import this results in an error because a filter with an empty CorrelationId is not allowed.
Deleting CorrelationId from the exported XML file, results in an error when trying to load the exported XML file because the CorrelationId is "missing".

Ah, also all the other filter properties are populated with empty values in the imported session filter.

You can always re-open it.
