    clutter/input-pointer-a11y: Fix dwell timeout start after moving pointer
    
    Sometimes the dwell timeout doesn't start again after quickly moving the
    pointer. That happens if `should_stop_dwell` returns TRUE for the last
    motion event we receive: It will stop the current timeout, but not start
    a new one until we receive another event where the moved distance is
    smaller than the threshold.
    
    To fix this, always call `should_start_dwell` and `start_dwell_timeout`
    instead of using an else-block, this makes sure we start a new dwell
    timeout still during the same motion event that stopped the old one.
