Improve order-invoice sample data

The initial work has been done in scope of MODINVOSTO-16 but there are some things which require corrections. Please refer to comments in the MODINVOSTO-16

Description:

• The invoice line (id=1bafe8ac-e7fd-437e-bfe6-4a94a01fb16e) for invoice 6b8bc989-834d-4a14-945b-4c5442ae09af is linked to PO Line which belongs to order with id=1d6a455f-29c5-4e51-84d9-e28450ef86ad i.e. order-invoice relationship is incorrect
• invoice line e0d08448-343b-118a-8c2f-4fb50248d672 has 2 fund distributions but linked PO Line only one (UNIV-SUBN)
• paymentStatus of poLine with id a0fb5514-cdf1-11e8-a8d5-f2801f1b9fd1 should correspond to state of invoice with id=40796c4a-ff0a-40ba-9a1d-c24c12dd4424
• invoice line with id=c8e41fdc-ae66-44a1-a194-bed0066672b6 covers 150 USD of the corresponding PO Line but there is no any adjustment but PO Line has discount and additional cost

Acceptance Criteria:

• Data samples between invoices and orders must be aligned
