HCAL tags fixed in POSTLS1 and STARTUP GTs

 Fixing the autoCond.py with the correct GTs for STARTUP and POSTLS1, containing correct HCAL tags for HO reconstruction in 70X. For reference, see HN: https://hypernews.cern.ch/HyperNews/CMS/get/relval/2804/25/1.html .

N.B. 'startup' workflow should run HCAL reconstruction using the simulation of HO for Run1, while 'upgradePLS1' and 'upgradePLS150ns' should use the new SiPM description. Switch in the code for that is supposed to be provided already.
