The Henry Draper stars are not stored in objectNames() hashes in
regular KStars, because there are so many of them, so it's a waste.
Besides, the Henry Draper index is an optional add-on for KStars.

Commit b32c941735317a4380ea615ef173ec25646db7d9 introduces a
regression by not falling back to finding by Henry Draper index.
