Jimmy Berry 5a2cd2dc9a osc-staging: handle select --move cleanup of empty source project.
- handle build disable in select command just like comment instead of
  stagingapi move_between_project() for consistency and to reduce double
  checking the same information via extra API calls
- build_switch_staging_project() provides target_flag parameter rather
  than trying to figure out flag value since caller has the context to
  know and again reduces API calls
- build_switch_staging_project() checking conditions are essentially
  checking if True is True since non-adi projects will always have ring
  packages or rings disabled entirely. The condition of interest is
  non-empty. Additionally adi projects are removed if empty so not a
  terribly useful distinction to make.
- provide helper update_status_or_deactivate() to handle common logic
  and replace in calling locations
