    Resolve empty drive displayed as blank minor logic issue (#152)
    
    The previous commit "Remove coding landmine in get_disk() (#152)" made
    an empty drive without a disk label (partition table) display as
    nothing, instead of the normal single unallocated partition with warning
    "unrecognised disk label".
    
    The previous commit said:
        3. The two remaining direct calls to get_disk() where the strict
           parameter is explicitly set to false, from set_device_from_disk()
           and detect_filesystem_in_encryption_mapping(), are when scanning.
           As the pass strict=false they don't allow the PedDevice deletion
           to occur if no recognised disk label is found.
    
    This is true, but get_disk(..., strict=false) additionally returned true
    even if there was no disk label.  And in set_device_from_disk() the
    empty drive case is inside the if branch of the get_disk() call
    returning true.
    
    Simply fix this by calling get_disk(), ignoring the return value.
    
    Closes #152 - GParted crashed when trying to probe an encrypted
                  partition containing content that libparted doesn't
                  recognise
