PPSR NZ interface; updates for Version 7.0.3 release

The NZ PPSR is due to release build 7.0.3 into production on 13th March 2019.

This version was made available for testing on the 28th February. In our testing we have found no issues.

However, the PPSR Transaction Report now includes additional Types of Transactions that were previously not reported upon. This change handles these new Transaction Types better, i.e. correctly reports the Transaction Type rather than "Unknown", and does not report that the Service Log doesn't exist. Note, this only applies to Transactions created after the new release.
