Bug 21301: Remove patron informations in reserves for GetRecords ILS-DI service

Actually, the GetRecords service gives many information :
borrowernumber (reserves field)

The issue data should not be sent by these service, its a privacy problem.

Test plan :
1) Enable ILS-DI webservice
2) Place hold on an item
3) Go to {opac}/cgi-bin/koha/ilsdi.pl?service=GetRecords&id={biblionumber}
4) Check the reserves tag content
