Allow unit tests to run without database connection

[jackbravo]

Today if you run npm run test you need to have a valid database connection. To verify this task you would need to turn off the database and run tests, and all tests should pass.

• Modify current existing tests to either mock anything that requires the database or that could be deleted. Or to not fail when the DB is turned off
• Modify our .github/workflow/deploy.yml file to not require a database connection when running vitest
