[FIX] mrp: product variant name in BOM structure report
[FIX] mrp: product variant name in BOM structure report

When printing a BOM structure using a variant,
the specifications of the variant were not
displayed in the BOM Structure lines,
making it different than what can be found
in the BOM structure form, and therefore
making it impossible to know which variant
has to be used for this BOM structure
from the report.
