[Katja Matthes]

For older magento versions (e.g. 1.4.2.0) inventory synchronization from OpenERP to Magento didn't work, because a helper method is missing: In old magento versions there is no function 'getProduct' in the catalog-product-helper.
Add code to bypass the call to missing function and search product manualy.

Thanks!
