Describe the Problem

When prefetching transactions with fallback provider, using const block = getBlock(blockNumber, true) resulting block does not contain prefetchedTransactions and fails with error when accessed block.prefetchedTransactions. This happens because FallbackProvider receives wrapped block from underlying providers and wraps it again
