Fix testing setup

[garyhtou]

There appears to be something wrong with our tests.

• The wrong database is being used
• We also get errors like Selenium::WebDriver::Error::UnknownError: unknown error: net::ERR_CONNECTION_REFUSED on CI

I'd also love to move to rspec + factory_bot

This seems to be a problem with GitHub Actions, as the tests run locally. Regarding rspec, this article pretty much captures my thoughts on it and unless there's a huge benefit that outweighs the complexity it adds, I'd prefer to stick with the default testing stack, at least for now.

@garyhtou what did you mean by using the wrong database?

Closing as tests seem to be working.
