Do not import from reco_objects_from_file when building HLT2 lines

Several HLT2 lines import upfront_reconstruction or make_pvs from the module reco_objects_from_file. This should not be done and be fixed, as the lines will not work in the real HLT2 like this.

A grep in Hlt2Conf/lines shows the following lines.
