"Lactase" entities not being normalized completely

[andrewsu]

From https://ui.test.transltr.io/demo/results?l=Lactose%20Intolerance&i=MONDO:0100345&t=0&r=0&q=027fec2a-2fba-4378-9092-abba65b6d96f, there are two results for "Lactase" presumably because of incomplete merging by nodenorm

I see this in test today, for Tilactase and Lactase: https://ui.test.transltr.io/results?l=Lactose%20Intolerance&i=MONDO:0100345&t=0&r=0&q=6d7d0527-38e0-42e3-9a17-e49952e7deee
