Fix SQLite SQL queries.

Some copy-paste errors made their way to those queries and prevented usage
of pgloader, but I missed that because I was using a previous version of the
query text files in my interactive environment.

Also, SQLite doesn't like the queries finishing with a semi-colon, so remove
them.

Fixes #747.
