This is the last of a sequence of PRs fixing contract logging. In this PR I fix printing of public contract function logs when a real transaction is sent (not a simple public function simulation).

This is the approach:

  1. When aztec node is started in test mode instantiate debugLogStore and thread it through all the relevant places,
  2. when this store is set, the logs get populated in it under the tx hash,
  3. then when getTxReceipt is called by the wallet the debug logs are returned in the receipt,
  4. if wallet receives any debug logs it prints them out.

Having the debugLogs on the TxReceipt is a bit messy but it's the only way how to not have to introduce another RPC call (it would made more sense to have it on getTxEffect otherwise as the debug logs are more of a tx effect). I don't think this matters much.

Note: The CI failure is unrelated failure on merge-train/fairies branch.
