Add on to commit be924b88. This fixes the situation completely where

a job could be accounted for more than it should in the _decay_thread
inside the priority/multifactor plugin.  Before the end_time_exp wasn't
stored for the job which was what was used to determine if the job was
already processed or not.  In 16.05 we were able to fix this mostly, but
for the TRES numbers they could get accounted for multiple times.  Since
a pack was needed to fix this we had to wait until 17.02.
