[JENKINS-55876] Recursive submodule URLs are not synchronized when changed on a checkout

If a submodule itself has submodules, and the URL of those submodules changes, then the second submodule's URL will not be updated.

This can cause checkout to fail, because the referenced commit may well not exist in the old submodule. This causes build failures, and either the workspace must be cleaned, or manual intervention must take place.
