Preserve work_item_types.old_id

What does this MR do and why?

We are fixing work_item_types table records to have IDs with fixed values in the range of 1-9. During the transition, by keeping an old_id column we will be able to fallback to the old_id when finding these records.

Later we can remove the column and fallbacks in the code.
