StoreGate aliases are persistified when writing out output. Although ideally we should be able to disable this, it's much simpler to just prevent reading the aliases. This will also enable us reading the old files which still have aliases.
This MR adds ability to disable aliases when reading a POOL file. @gemmeren, what do you think about this change?
The use case is that some aliases might conflict with the scheduler (especially for the xAOD::EventInfo instances).
