C4::Circulation::GetItemIssue returned all the issue and item
informations for a given issue. Moveover it also did some date
manipulations. Most of the time this subroutine was called, there
additional information were useless as the caller usually just needed
the basic issue's infos 'from the issue table).
This first patch updates the simple calls, ie. the ones that just need
the issue's infomations.
Test plan:
The following operations should success:
- transfer a book
- create a rule for on-site checkouts and confirm that a patron cannot
check more items out that it's defined in the rule.
- Renew an issue using ILSDI
- Using SIP confirm that you are able to see your issues
