[tor-commits] [arm/master] fix: skipping init actions that will fail

    fix: skipping init actions that will fail
    
    When we start and are detached from tor many actions (bandwidth prepopulation
    and loading the torrc, for instance) will always fail. Skipping these actions
    if there's no tor instance to avoid pointless work and log messages.
