Values in convention result file are separated in inconsistent way

[kokosing]

See the example:

-- delimiter: |; types: BIGINT|BIGINT|INTEGER|DOUBLE|DOUBLE|BIGINT|BIGINT|INTEGER|DOUBLE|DOUBLE
1|1569|1|212.000000|1.6302135196395|1|1569|2|239.250000|1.2641513267824|
1|5627|1|282.750000|1.5657032366347|1|5627|2|297.500000|1.2084286841446|
1|7999|1|166.250000|1.7924231710846|1|7999|2|375.333333|1.0080922644484|

Row values have to finish with delimiter while column types have to not.
