    view-source-handler: don't lose port number when comparing views
    
    We fail to find an existing tab displaying the target URI if it includes
    a non-default port, because soup_uri_set_scheme() resets the port to use
    the default for the given scheme.
    
    Credit to crvi for debugging.
    
    Fixes #1076
