refactor(tests): collapse duplicate entry-point asserts to loop

Found via /simplify reuse + quality review of PR #22. Pure deduplication
of the configparser-based entry-points assertions added in 78afc07 — the
only thing varying between the two asserts was the CLI name lookup key.
Saves 3 lines, single point of maintenance, no information loss on
failure (the loop iteration variable appears in the assertion message).
