    polkitAgent: Reset the session request timeout when removing it
    
    When handing the resetDialog request we're leaving a source ID alive,
    leading this error:
    
    (gnome-shell:22464): GLib-CRITICAL **: 17:46:11.065: Source ID 12934 was not
    found when attempting to remove it:
    
    == Stack trace for context 0x55c9246916c0 ==
    #0 55c9249151b8 i   js/ui/components/polkitAgent.js:391 (11f71fd544c0 @ 100)

    #5 55c924914f78 i   js/ui/environment.js:149 (1c9e50a8d9e8 @ 14)
    
    So, reset the source handle to avoid trying to remove it.
