Implemented method "getSellerTradePartyAddress" to ZUGFeRDImporter.ja…

…va which gets an instance of PostalTradeAddress.

Removed method "getISODate" from last Commit due lack of implementation - will be implemented at a later time.
Also Added Tests for "getSellerTradePartyAddress" to match ZF1 and ZF2
