patch 8.0.0970: passing invalid highlight id

Browse Source 
Problem:    if there is no StatusLine highlighting and there is StatusLineNC
            or StatusLineTermNC highlighting then an invalid highlight id is
            passed to combine_stl_hlt(). (Coverity)
Solution:   Check id_S to be -1 instead of zero.
