handle tree errors gracefully

[mattsse]

we currently have some unwraps:

reth/crates/engine/tree/src/tree/mod.rs

Lines 859 to 863 in 9b3a011

	self.buffer_block_without_senders(block).unwrap();
	PayloadStatus::from_status(PayloadStatusEnum::Syncing)
	} else {
	let mut latest_valid_hash = None;
	let status = match self.insert_block_without_senders(block).unwrap() {

TODO
