Necessary Maintenance #19431
Remove BackTrackerService from reconstruction configuration files when it's not needed any more
From Dominic Barker (ServiceNow ticket RITM0661476):
Due to the requirement to have backtracker in the EM_Shower_module (see ticket RITM0661275) I have added the backtracker service to the standard_reco_sbnd_basic.fcl. Once the backtracker requirement is removed from the module this is a reminder to remove the backtracker and particle inventory service from the fcl file.
