David Roberts 051b0b8d2f Bug 22470: Missing the table name on misc/migration_tools/switch_marc21_series_info.pl
This patch adds the table name to the SQL update statements.

To test:

1) Apply the patch
2) Run the script. Check that there are no errors, and that the script
behaves as expected.

Signed-off-by: Andreas Roussos <a.roussos@dataly.gr>
Created a test record with values in field 440. Applied the patch, ran the
script with the -c -f flags and observed that the values were moved to field
490. Also, the relevant Koha to MARC mappings were changed accordingly.
