Implement some tests

[vorugantia]

Right now, the spec.ts files generated by angular-cli's ng generate are not running any useful tests. We want to implement unit tests on each component's and service's specific variables, routes, etc.

See these guides:

We will not have time to figure out how to test an Angular app well and implement tests.

If possible, we should try to find the time to add a few very high-level tests Navigate to a given URL and check that some content is on the webpage.

E.g. navigate to /cat/2fhl/2 and check that Source Name: 2FHL J0018.5+2947 is on the page. @vorugantia - Do you know how to add such a test? Can you try to add this one example?

High-level tests have been implemented in #77 and #79. These are e2e tests that route to a certain page and check for content, etc. Later on we can add unit tests, but I see that as lesser priority until we get all of the content on the webpage.
