DEFECT: Can't see content of received requests from the REST Mock transaction log

When running REST Mock listeners in SoapUI 5.3, I've found that we cannot double-click the request from the transaction log to see it's contents--nothing happens.

Compare to Soap Mock listeners, when you double-click them, an extra window opens that allows you to see the message and response.

This is only a problem in SoapUI 5.3.  ReadyAPI does correctly allow you to see the content of received requests for REST mock listeners from the transaction log.

Reproduce:

1. In SoapUI 5.3 run a REST Mock listener
2. Send a message to it
3. In the listener's transaction log, double-click the entry for the received request to try seeing it's contents
