Bug 19198: Renewal as issue causes too many error

This patch moves some code and prevents checking for too many checkouts
when performing a renewal via checkout

To test:
1 - Set a rule to limit checkouts to a single issue, allowing renewal
2 - Issue an item to a patron
3 - Issue the same item
4 - In staff client you get a confirm to renew and a notice of Too Many
checkouts, don't confirm
5 - VIA Sip - you get a renewal response, but in logs the renewal fails
as a 'too
6 - Apply patch
7 - Via staff client you shoudl get renewal confirm with no too many
error
8 - SIP checkout should renew
