It is cleaner not to carry mutable state (sponsorshipIndex) between blocks.
It is currently being set in block 1, and being reused in block 2.

We can initialize it with the value, something like: auto const sponsorshipIndex = to_string(keylet::sponsor(alice.id(), bob.id()).key);

and verify it in both block 1 and block 2.

{
// Request by sponsor and sponsee.
json::Value jvParams;

jvParams[jss::sponsorship][jss::sponsee] = bob.human();
