Side Bar explorer Folders collapse if a remote connection is reconnected

Issue Type: <b>Bug</b> In the last version when a remote connection was reconnected the folders that where open stayed open. In the latest release whenever there is a reconnect all folders get collapsed again. This is when the alert window "reload/reopen" is run. A normal timeout and reconnect does not trigger this.
