ZUGFeRD2PullProvider needs getDueDate() although getPaymentTermDescription() is defined

[heisej]

When using getPaymentTermDescription() to specify the payment terms one still has to define getDueDate() as well.
This is caused by following lines where paymentTermsDescription is always 'null' for the first if-block. Therefore the fallback string is constructed in any case before even testing for a supplied description.

Exchanging the two if-Blocks would correct both issues and be the correct way to implement this.

Lines 255 to 261 in 496c6bd

	if (paymentTermsDescription==null) {
	paymentTermsDescription= "Zahlbar ohne Abzug bis " + germanDateFormat.format(trans.getDueDate());
	}
	if (trans.getPaymentTermDescription()!=null) {
	paymentTermsDescription=trans.getPaymentTermDescription();
	}
