Enable creation of muon raw data cache containers in MuonConfig package.

The various bytestream decoding Cfg functions in MuonConfig were assuming the prescence of the new muon cache containers for MDTs and CSCs. This caused errors in the trigger tests (e.g. http://atlas-computing.web.cern.ch/atlas-computing/links/distDirectory/gitwww/GITWebArea/nightlies/master/2019-01-27T2257/Athena/x86_64-slc6-gcc62-opt/Athena/UT/TrigUpgradeTest.log.html) because the tools assumed the cache containers exist, but the algorithm to create them was never scheduled. This is now fixed by scheduling that algorithm insiide the Cfg functions for the MDT and CSC decoding. This also means it is no longer needed to schedule the cache creation algorithm by hand in the testing functions (and the corresponding reference files are updated).
