Add auth tests

[Timothy-Gonzalez]

Adds tests for every auth endpoint, and fixes a lot of stuff (blame: @AydanPirani, test your stuff!)

Resolves #108

• auth-lib.ts
  • getJwtPayloadFromProfile
• auth-router.ts
  • GET /auth/test/ was only used for testing
  • GET /auth/login/github/
  • GET /auth/login/google/
  • GET /auth/:PROVIDER/callback/:DEVICE/
  • GET /auth/roles/:USERID/
  • PUT /auth/roles/:OPERATION/
  • GET /auth/list/roles/ no current use, no practical use
  • GET /auth/roles/
  • GET /auth/roles/list/:ROLE/
  • GET /auth/token/refresh/

Most of what is not covered is error handling, which is really hard to mock. My upcoming error handling pr fix should solve this.

I am taking a break from jest testing after this.
