Issues with machine translated jobs

Problem/Motivation

When requesting a job to be machine translated, the item ID is not set correctly. This causes various errors, like missing array indices and requesting information from a non existing URL. The item ID is incorrect in the tmgmt_remote table, so it probably is never set correctly (it's always N, for all items)

Proposed resolution

Set the item id correctly, test, provide patch, review and commit it.

Remaining tasks

Find where the item id is set, figure out why it only happens with machine translated jobs.
