chore: fix tests

- deleted: test/network/registry.js
Test was not actually working anymore since the cwd it uses no longer
exists (`node_modules/npm-registry-couchapp`) in the file system.
Removing to clean up future test runs.

- changed: test/tap/git-npmignore.js
Just make sure the test commit in this file does not tries to use gpg
signatures in case the user has that option active.

- changed: test/tap/splat-with-only-prerelease-to-latest.js
Updating comparing values to use `https` instead of `http`.
