Incorrect Block Profit if Builder Wallet receives funds and the same block is built by builder

[MPLA101]

As per the documentation

• We reserve gas for the proposer payment using proposerTxPrepare and commit proposer payment after txs are added with
  proposerTxCommit. We do it in a way so all fees received by the block builder are sent to the fee recipient.

If the builder writes a block and that block has a transaction that sends funds to the Builder coin base, the whole transaction amount is considered as a block profit.
