[Gui] Always hide progress bar on finished load

The loadFinished signal from QtWebEngine includes a boolean indicating
whether the load was "ssuccessful" or not, but no apparent way to
determine what error, if any, occurred. Given that we are never
displaying any error information to the user, hide the progress bar
regardless of the success or failure of the operation.
