    list-base: Stop listening to "enter" signal for GtkDropControllerMotion
    
    Now that we are listening to the "motion" signal when hovering over
    folders, it's no longer necessary to listen to "enter" since we are
    focused on movement rather than absolute location.  Furthermore,
    the "enter" signal produces unexpected results when hovering,
    switching to a new folder, hovering over another folder and
    unexpectedly switching again (this doesn't happen with the "motion"
    signal).  Stop listening to the "enter" signal.
