work around https://bugs.python.org/issue41638

[WolfgangFahl]

When a column-value is missing in one of the records in list of records the error message of the python library is:

sqlite3.ProgrammingError: You did not supply a value for binding 2
This is not helpful - improve the error message as asked for in https://bugs.python.org/issue41638 - workaround the problem as long as it is not fixed upstream.

Step 2:
improve with a message like:
INSERT INTO Pokemon (name,type) values (:name,:type)
failed: no value supplied for column 'type'

Step 2:
improve with a message like:
INSERT INTO Pokemon (name,type) values (:name,:type)
failed: for record #2 name='Raichu': no value supplied for column 'type'
