FIX: correct handling of replica caches when more than 5000 files
typo + add counter of removed files from cache
Bugs in gLogger usage

instances does not exist, only step_instances
setParents does not exist, only setParent
Protect against missing MetaData, e.g. GUID empty string
PRODUCTION_ID and JOB_ID are taken from workflow_commons (cf. test_modules wf_commons)

in the wrong place.
