    Fix adjust_sql_option_string test on Windows.
    
    The linkage problem was caused by the symbol appearing in
    libgncmod-backend-dbi.dll but not libgncmod-backend-dbi.dll.a.
    Incoprorating gnc-backend-dbi.c as a source file to the test program
    instead of linking its library resolved the issue.
