[RM-8631] [Bug] get_short_attribute function from AbstractOutput (pylibamazed) can't reach linecatalog

While testing export_attributes cli function from AmazedOutputAnalyzer in develop, I noticed that trying to get information about Halpha line (which I know is in the dataset I used, sp8_pfs) raised an error : @INTERNAL ERROR:Line Halpha not found in {}@. I need to gather further information on this, but this behaviour does not occur on master. My guess is that somehow, the function cannot reach the linecatalog anymore but I have yet to debug that
