Motivation
In 2.7 there's a bug that leave the Namespace bundles cache to not to be invalidated after a namespace is deleted.
If a namespace is deleted and recreated with a different number of bundles, that will lead to ownership issues.
The main problem is that we're invalidating the bundle cache immediately and it will get re-insterted with the old version of the z-node, therefore discarding the new updates.
This is targeting branch 2.7 since the code has changed quite a bit in 2.8. I'll also add the same test in master branch.
