PullRepo should not delta

[ikeydoherty]

If we do a pull that results in 320 jobs, and average each sync job as ~11s, this is an hour added for no reason. Sure, it might not always index because deltas existing or not needed, but still, optimise it.

Just swap it out for a DeltaJob and then we can manually index it once status shows it done.

Marking it here so i don't actually forget..
