Use test URLs that are less likely to disappear

Use test URLs that are less likely to disappear

Avoid 404 errors in stable when upstream reorganize the test data
(happened to two of these in 0.25 -> 1.0).

It is _not_ necessary to update the tag version on every package release,
only if these tests fail because they expect moved/changed data.
