    alternative-status-menu: fix criticals when opening the menu
    
    After enabling, the user menu was keeping a reference to a
    destroyed actor, and then was updating it from signals. Updating
    this (a StEntry) caused g_criticals because of a NULL ClutterText.
    Instead we can null out the actor entirely, which will stop
    the signal handler from doing any harm.
