Message logged for each model save event when no server connection available

With no server defined or server disconnected, there is a log message for each model save event.

No Teiid Server found (server not started)

This is occurring because ModelChangeJob is creating and executing a UpdatePreviewVdbJob which performs the check and ends up logging an INFO status.

Users don't really need to know this unless they attempt to preview and a dialog is in place to inform them of no server.
