Upgrade to 1.10 fails if there are orders with orderers that have no provider accounts
TODOs:

• Add a precondition that ensures all orderers have provider accounts
• TRUNK-4396 should be done to proceed with this ticket
• The changeset that checks if there any orders with no orderer needs to also make an extra check for the existence of the ''Unknown Provider" account, if it exists, then the changeset should pass
• Set the orderer field for orders with no orderer to the providerId of 'Unknown Provider' row
• Remove changeset that inserts provider rows for orderers with no provider accounts
