syncTree() could use one more log message

[pinheadmz]

This function can take several seconds and should log something before it starts so impatient users don't think their process is borked:

hsd/lib/blockchain/chain.js

Lines 124 to 154 in e8c9632

	/**
	* Sync tree state.
	*/
	async syncTree() {
	const {treeInterval} = this.network.names;
	const last = this.height - (this.height % treeInterval);
	for (let height = last + 1; height <= this.height; height++) {
	const entry = await this.db.getEntryByHeight(height);
	assert(entry);
	const block = await this.db.getBlock(entry.hash);
	assert(block);
	const state = await this.readDeploymentState(entry);
	assert(state);
	const view = new CoinView();
	const hardened = state.hasHardening();
	for (const tx of block.txs)
	await this.verifyCovenants(tx, view, height, hardened);
	assert((height % this.network.names.treeInterval) !== 0);
	await this.db.saveNames(view, entry, false);
	}

	}
