`convertLegacyUtilityTypes` codemod replaces types with others from a random file

[mwiencek]

Flow version: 0.312.0

Not sure if this is an issue with codemods in general or just the convertLegacyUtilityTypes one, but it seems to be completely broken (see the linked repo).

It doesn't always take the types from A.js. It may randomly take the types from B.js or C.js instead.
