soroban-rpc: Fix upstert bug in DB cache

[2opremio]

Leftover from #837

BTW, the fact that the system tests are failing all the time gets the eye used to seeing red-crosses in CI. This lets problems like this leak through the cracks.

We should probably make the unit tests mandatory for merging although I would prefer for the system tests not to be broken so often (CC @tsachiherman @sreuland )

ok, can take a look at e2e tomorrow, in the ci output, the rpc ingestion is logging xdr parse errors, maybe we need to bump the go pkg ref, cor core version, etc.

I'd suspect that the js soroban client version doesn't point to a hash that matches the latest xdr.

Yeah, see #846
