SQLite3 tests fail because "new_product_users already exists"

[jamis]

This is because of this commit to ActiveRecord, from 2014:

https://github.com/rails/rails/commit/bbf6df78a42345eb5343337372fb8602b736222e

The adapter's #tables method is explicitly checking for both tables and views (even though the schema dumper won't handle the views correctly).

Fixed with #15
