Bug 32250: (follow-up) Commit background job to the DB

Bug 32250: (follow-up) Commit background job to the DB

We can't run a background job if it isn't in the database, however,
this script runs with AutoCommit disabled. We need to enable it while
generating the background job, then disable for the updates.

I don't nkow if using a transaction would be preferable.

I tried to solve this independently, but it requires consolidating the
index requests to make this work easily
