[IMP] l10n_in_edi: check ship from address name is must set

Current behaviour before PR:
  1.Go to Company Partner
  2.Create a shipping address
  3.Set this shipping address in the warehouse
  4.Create a sale order with that warehouse
  5.Create an Invoice
  Then that invoice can't be send because the address name is empty.

Current behaviour after PR:
  If anyone creates a contact under the company as the shipping address and if
  the name is empty then in this case it assigns the company name
