Deleting workspaces does not delete styles

[AlexGacon]

Context:

GS Cloud with JDBC config and JDBC resource store
Data are stored in a Postgis Database

Reproduced with:

GS Cloud RC1.28 on Kubernetes deployed with Helm charts
GS Cloud RC1.28 on Docker deployed with docker compose
GS Cloud RC1.29 On Docker deployed with docker compose
GS Cloud master code from GitHub deployed with docker compose

When I ask to delete workspaces, the styles attached to the workspaces are not deleted : they are simply moved outside the workspace and are style available in the style list. I have to manually remove the styles to have a clean GeoServer configuration.

The same operation on a vanilla GeoServer deletes the styles as expected.
