    Prevent key-only inserts for new rows during import
    
    Closes #103
    
    - The set_slice() later in import_fields will create the new records
      just fine.
    - Tested with MySQL by uploading a spreadsheet with new rows for a table
      with a foreign key.
    - Also tested with a table with an auto-incrementing key.
