portalHelper: Don't change the main window title

Browse Source 
The title of the window should not be in control of a potentially
hostile hotspot provider, so only set the subtitle to be that of the
page, the main title will stay the same.

The subtitle will also be set to a URI, so that the hotspot cannot be
used to control the title shown in our UI.
