Bug 32804: (QA follow-up) Typo ahs and fix ImportBatch.t

Resolve:
    #   Failed test 'Item's biblioitemnumber has not changed'
    #   at t/db_dependent/ImportBatch.t line 407.
    #
    #          got: '4261'
    #     expected: '2371'

Do not compare $item1->biblionumber with $original_biblioitemnumber :)
