Converter generates buggy vault packages

The way the converter generates the empty hull packages for the flattened container package is flawed as vault doesn't handle the filters correctly. Vault expects the structures that are covered in the root paths of the workspacefilter to be present otherwise the importmode = merge is getting ignored.

To avoid this issue I suggest to set a global filter to the root path that excludes everything and has importmode merge - this will not create any significant snapshot packages even if manually installed and won't be misinterpreted by vault.
