MB-19339: Drop override for internal clients
MB-19339: Drop override for internal clients

A while back I added an automatic fallback which would give
all internal clients full privilege sets given that
the other internal components wasn't RBAC aware. It turns
out that currently no one is setting that flag, so the
code would never be executed. Given that our external
end to end tests currently pass they do get enough
privileges as of today so we shouldn't give them
the oportunity to get more privileges ;-)
