Fix crashes if TPC not in data taking or AliTPCdataQA info not available
Fix crashes if TPC not in data taking or AliTPCdataQA info not available

o The trending failed in case the TPC was not in the data taking
  due to the access of non existing OCDB Entries
o After implementing the cross-checks for the active channel map
  crashes occured in the QA which were traced back to null pointers
  in the AliTPCdataQA OCDB entries. A protection was added
o ATO-215
