"""BUG-1180: a Mahapurusha planet must not count itself as the malefic conjunct with it.

Before 57782aea ``_has_malefic_aspect`` skipped ``pn == planet_sign`` (a planet name
compared with a sign name, never equal), so Mars and Saturn -- natural malefics --
always "afflicted" themselves and Ruchaka / Shasha were never valid. The fix passes
the yoga planet and skips it. Fictional placements; no birth data.
