Fix CI warnings for builds without AIDA

This MR improves the handling of builds without AIDA and fixes tests and a few small issues:

• clean up and general fixes
  • remove obsolete test reference files
  • fix handling of failures when retrieving HistogramDataSvc
  • do not retrieve HistogramDataSvc if histogram persistency is not required (this causes a massive update of reference files)
• fixes for no-AIDA builds
  • added to no-AIDA builds components that were wrongly disabled
  • fix GaudiPythonDict dictionary selection to avoid warnings
  • disable tests requiring AIDA (and fixed one)
  • stop ignoring failures in gitlab-ci for no-AIDA

Closes #357 (closed)
