Subject: [PATCH] Use valid measurement names in csv parser (#5577)

If an empty column is present in parsed csv data, a `recordFields` is
set to the key of "". If no `MeasurementColumn` is defined, this empty
value was being used as the measurement name. By only setting the
measurementName if the value is not empty, we avoid this error.

Since an empty column is a valid column, skip values must account for
them.
