When two BOM rows named the same drawing file and shared a material and
thickness (the same part in two subassemblies), Create Nests imported
the file twice. Nest.Drawings is a set keyed by drawing name, so the
second drawing was dropped with its quantity: PT01 x2 plus PT01 x3
gave a nest needing 2, while the Groups tab showed 5.
Each drawing file is now imported once and needs the total of its
rows. Build_CombinesRowsThatUseTheSameDrawing required [2, 1] where
[5, 1] was expected against the previous commit.
