patch 8.1.0750: when the last sign is deleted the signcolumn may remain

    patch 8.1.0750: when the last sign is deleted the signcolumn may remain

    Problem:    When the last sign is deleted the signcolumn may not be removed
                even though 'signcolumn' is "auto".
    Solution:   When deleting the last sign redraw the buffer. (Dominique Pelle,
                closes #3803, closes #3804)
