[BUG] injecting split and retry via injectRetryOOM triggers for withRetry that can't handle it

[abellina]

The reason OOM injection works with CI is that we inject OOM in those places that can handle it (they have a withRetry). Recently, we added the ability to inject a "split and retry", however, we are not triggering these exceptions when inside of a withRetry that has a split function defined, instead we inject these for all withRetry flavors, which I don't think is what we want.

I would like to change the injection mechanism for split and retry so we make sure we don't inject if our scope isn't ready for it.
