[Jiří Techet <jiritechet src gnome org>]

commit 594e04c91f23321b3c774e8507832faad1ee746c

    Update documentation of proxy-uri property.
    
    SoupSession resolve the default proxy when the proxy-uri
    property is absent. Setting the proxy-uri will override the
    default proxy.
    
    This patch updates the doc to make that apparent.
