tests/shadow-testing: wait for updateVerifier tx to seal before addProver

The impersonated eth_sendTransaction for updateVerifier could still be
in the txpool when addProver signed with the same owner nonce, failing
with 'replacement transaction underpriced' (hit twice at bring-up).
Poll for the receipt before continuing.
