DATABASE_MATCH via MIM curation (#114)

A MES buffer is a prepared solution of MES, not the MES compound: the record's ingredient_type is STOCK_SOLUTION while the CHEBI:39010 MES record is SINGLE_INGREDIENT. merge_unmapped_into_mapped correctly refused to fold one into the other. Follows the established stock-solution convention here — 12 of 19 mapped STOCK_SOLUTION records hold a kgmicrobe.ingredient: mint with a match to the compound (#114).
