Do not always update when used with track_changes: true

Problem/Motivation

When used with track_changes: true in the migration, the already imported items will always be updated even they didn't change.

Steps to reproduce

- Create a migration with track_changes: true an a migrate_source_queue source
- Create items in the source queue
- Run the migration: drush migrate:import my_migration => the items are created
- Add again items in the source queue, with the same data
- Run the migration again: drush migrate:import my_migration => the items are updated but they shouldn't since they didn't change

Proposed resolution

I have no idea so far. track_changes: true seems to use the whole queue item data, which includes data which is unchanged, but also item_id and created which change each time. Those last 2 are used in the computation of the hash, so since they change, it's considered as a change even if data did not change.

I quicky tried to remove them from the data passed to migrate but I was stuck with the fact that migrate needs the item_id to remove it from the queue.

Remaining tasks

- Find out if it's possible
- Code it
