Fix to run full HLT1 sequence when muons are in local
After !968 (merged) , most hlt1 sequences were not crashing when the required sub-detector raw banks were missing. The only exception to this was the muon decoding, which continued to be run (and crash) even without muon raw banks.
This MR implements a fix in the muon decoding for the commissioning period, in order to enable hlt1_
sequences to be run at all times without crashing. This will allow the PHYSICS activity (which is switched automatically at stable beams) to be set by default to the tracking sequence.
Closes #406 (closed)
