Make the GET /resources endpoint public, and update tests

[lpatmo]

Context

The GET /resources and a GET /resources/{id} required user authorization. But ideally, we want non-logged-in-users to be able to search and look at resources. They should only have to be logged in if they want to delete, create, or edit a resource.

@chris48s and @BethanyG did most of the heavy lifting with tests already; I only followed the same pattern.

Feedback welcome!

Note: I left POSTing a resource as a later todo, since it is blocked by https://github.com/codebuddies/backend/issues/125.

Before & After

Before: GET /resources and GET /resources/{id} hidden under a token

After: GET /resources and GET /resources/{id} available to users without a token

Implementation

[x] Make GET /resources not protected by authorization [x] Change setup for tests to make sure we're not authed for the GET requests, but are authed for PATCH, and search. [x] Add test to make sure GET /api/v1/resources/{{guid}}/ and GET /api/v1/resources/ requests and search work without a token [x] Add/alter tests for GET GET /api/v1/resources/{{guid}}/ and GET /api/v1/resources/ requests and search to ensure that they also work with a token [x] Add tests to make sure PATCH and POST fail without a token [x] Add test to make sure DEL fails without a token

Personally I find reducing each test case to the bare minimum makes it easier to read/understand

That is excellent feedback, thank you! Will take a look/improve this tonight...
