Stefan Seifert resolved SLING-7880.
-----------------------------------
Resolution: Fixed
fixed:
https://github.com/apache/sling-org-apache-sling-tenant/commit/80853919ca46788370ed98cce593345fad19d458
in this case it's safe to assume that the user has not tenant context, as it's
a system user and has not even access to it's own home directory. this should
*not* be logged as error.
