Unit tests

[Arshad-Zaman]

I did the following:

• rewrote some old tests so they run on github actions
• made a db testing environment in memory to test db queries
• added tests to signup new user and log in that new user
• added front-end tests for checking form components

If all seems good, give let me know and I'll merge.
