In ModuleUtil.bootstrap(), we try to create the parent of to-be-imported nodes before delegating to the actual import code (DataTransporter.importXmlStream), but
1- this is always done in the "config" repository (same bug as MAGNOLIA-1326)
2- not visible since done in the system session, which happens to be never same afterwards in most cases *

this is useless since DataTransporter.importXmlStream does it (and in the correct repository this time!)

• It only becomes visible if by chance, after bootstrapping nodes outside the config repository, another module bootstrap files again in the config repository, and thus saves it.
