Viewing conn Detail in one Query Session makes Correlation "Not available" in another

[philrz]

Repro is with commit 6a90407. It looks like this issue may not be new, but I happened to notice it while paying close attention during the verification of the fix to #3101.

The attached video shows the repro steps using the attached test data conn.log.gz and ifconfig.pcapng.gz. As the latter is a pcap, it must be uncompressed before loading.

Steps:

1. Load both files into their respective pools.
2. Open a Query Session to the conn.log.gz pool and observe the Correlation in the Detail pane when clicking each conn record
3. Open a separate Query Session to the ifconfig.pcapng pool and observe the Correlation in the Detail when clicking its conn record
4. Click back to the Query Session for conn.log.gz pool and click the conn records again

At that last step, the Correlation views show "Not available", which is unexpected.
