_context.py: Don't call utils._get_bst_api_version() at load time.
Getting the version requires importing the __version__ module which not
available at bash completion time, and we need to load the buildstream.conf
file when completing artifact names (because the config may determine where
the local artifact cache resides).
This fixes stack traces which were occurring in `bst artifact checkout <TAB>`
