Duplicate primary key entry in template_copies

[JosephSemrai]

Upon trying to upload a CSV file under 50 lines and viewing it using visualizedata, I encounter the following error involving a duplicate primary key entry in the template_copies table.

This was reproduced by following the directions on the README file and restoring the database dump.

Traceback

MySQLdb._exceptions.IntegrityError: (1062, "Duplicate entry '1' for key 'PRIMARY'")

The above exception was the direct cause of the following exception:
