Domain improperly extended during changes vs ROLIE feed checks

[JanHoefelmeyer]

The same domain can often be referenced to via different strings.

These should be handled the same, but are not in regards to checking whether the files within the ROLIE feed and the changes.csv are identical.

For example, using the localhost setup created via the setup scripts, creating an accurate changes.csv, the tests using "localhost", "127.0.0.1" or the direct "localhost/.well-known/csaf/provider-metadata.json" will fail, e.g. with the error messages

(In 13: )"https://localhost:8443/.well-known/csaf/white/2021/rhsa-2021_5217.json in ROLIE, not in changes.csv"
(In 15:) "https://csaf.data.security.localhost/.well-known/csaf/white/2021/rhsa-2021_5217.json not in ROLIE, in changes.csv"

Using the domain "localhost:8443" however will pass the test as expected.
