nano-nit: is root_span the right name? should this be target_span or something?

Could be either; I think root_span makes sense because in the case of S3, the parent_span is the root span if it exists; if it doesn't exist, then the span is the root span of the trace

What does this PR do?
Put span pointers on inferred (root) span instead of the lambda (child) span, as discussed in Slack.
Note that moving the location of the span pointer has no actual effect on the functionality and requires no changes on the UI side. As long as a span is found with a matching hash, span pointers work. Since the spans are on the same trace, this has no noticeable change for our users.
Motivation
Discussed in Slack; this change just aligns span pointers with bottlecap (universally instrumented) runtimes.
Testing Guidelines
Manual testing. See this span and you will see that the span links are on the inferred span now.
