Uncomment and fix a settings-view package test

[DeeDeeG]

A quick follow-up to #307.

What this fix is all about (click to expand):

There is a special handling of internal/bundled packages which specify their repository field of package.json as the exact GitHub repo URL of the main editor...

The editor (specifically some logic in the settings-view package, I guess) understands that bundled packages with "repository": "https://github.com/pulsar-edit/pulsar" should link to this repo's packages/[package name here] subdir, not just to the root repo URL as specified verbatim in the package's package.json, i.e. https://github.com/pulsar-edit/pulsar

This updates the dummy spec package used for this spec to have its repository URL be https://github.com/pulsar-edit/pulsar instead of the old https://github.com/atom/atom. Which, after this change, then matches with the editor's own repository URL in its own package.json. So the test, which assumes the special handling described above is in play, works as intended again and passes.

---

So this fixes a test that been failing and which got commented out during #307. (The fix is essentially a tiny re-branding task.)

This gives us one more test running, one more test passing. Not a huge deal, but feels better than just commenting this one out, and I got the fix sorted relatively quickly, so here we are. Figured I may as well submit this as a PR.

Looks like an easy approval from me! More passing tests and a small change, couldn't be more awesome

Thank you for the review!

Merging because: Very very small fix, it works for me locally, and now in CI as well, and I confirm editing it to be wrong again (by typoing the repo name) makes it fail again, so that proves it's not a false-positive... And now I have an approve. Merge time!
