bitbake: persist_data: close connection in SQLTable __exit__

A Connection's __exit__ does not close the connection, but rather deals
with transactions. See https://docs.python.org/3/library/sqlite3.html#how-to-use-the-connection-context-manager

This change is not necessary on 'master' because persist_data was
removed.
