Bug 7241: circulation action logs record biblionumber instead of item number

Issue log and and circulation logs are incorrectly recording biblionumber instead of item number, creating incorrect logs.
This patch corrects this, and modifies the action_logs table in two ways:
- the timestamp is not updated anymore with UPDATES (but still automatically filled when INSERTing)
- to partially correct the broken logs, the log history is filled with the first found item for each biblio
