fix for Tile and L1Calo hold trigger sources

In R2 the detector list taken from the BUSYCONF folder was also used to insert the hold trigger information. During the 2020 May testing runs for R3, there were some HT periods that were not counted by the app. These were inserted under the TIL and L1CALO sub systems. But the app was expecting "Tile EB" or "Tile LB" and "L1Calo" as per the BUSYCONF naming.

I have inserted a new detector in the detector list to account for the general Tile HT info (not divided into LB and EB) and fixed the all-caps naming of L1Calo to match the BUSYCONF naming.
