ExecutionOutcome may return a wrong block count

[joshieDo]

Describe the feature

We call the following method to get the block count of a ExecutionOutcome :

reth/crates/evm/execution-types/src/execution_outcome.rs

Lines 226 to 229 in 33bf34b

	/// Number of blocks in the execution outcome.
	pub fn len(&self) -> usize {
	self.receipts.len()
	}

However, we do not enforce/validate self.receipts during initialization. For example, if the Receipts is initialized as follows, ExecutionOutcome::len() will be 0 since self.receipts will be an empty vec.

reth/crates/storage/db-common/src/init.rs

Lines 246 to 253 in 33bf34b

	let execution_outcome = ExecutionOutcome::new_init(
	state_init,
	all_reverts_init,
	contracts,
	Receipts::default(),
	block,
	Vec::new(),
	);
