bc3a8eadd1 removes the n-obj service
from jobs in master but keeps in the stable branch jobs. However,
several of the job definitions were not concatenating it correctly
on the stable branch definition so some services were not starting,
like n-net, which leads to very bad things on stable branch jobs.
