Follow-up from "Drop "Line" suffix in line names"

The following discussion from !1730 (merged) should be addressed:

  ... the tests in MooreAnalysis were failing because they are using Hlt/Hlt2Conf/python/Hlt2Conf/lines/Bs2JpsiPhi.py which I thought could be removed as it's a deprecated example.
  Do you have time to update the tests with the more recent starterkit examples (in a separate MR)?

To do:

• remove LoKi-based Hlt/Hlt2Conf/python/Hlt2Conf/lines/Bs2JpsiPhi.py example in Moore
• update MooreAnalysis to use the more recent Hlt/Hlt2Conf/python/Hlt2Conf/lines/starterkit/bs_to_jpsiphi.py
