Set zero power snapshot balance when balance aggregator doesn't return any balance for an address

[aminlatifi]

impact-graph fills power snapshot balances by querying the balance aggregator as below

impact-graph/src/services/cronJobs/fillSnapshotBalances.ts

Lines 124 to 143 in bc3b435

	const balances =
	await getPowerBalanceAggregatorAdapter().getAddressesBalance({
	timestamp,
	addresses,
	});
	const groupByWalletAddress = _.groupBy(batch, item =>
	item.walletAddress.toLowerCase(),
	);
	const snapshotBalances = balances
	.map(balance =>
	groupByWalletAddress[balance.address.toLowerCase()].map(item => ({
	balance: balance.balance,
	powerSnapshotId: item.powerSnapshotId,
	userId: item!.userId,
	})),
	)
	.flat();
	await addOrUpdatePowerSnapshotBalances(snapshotBalances);

When the balance aggregator doesn't have any balance for an address, it doesn't return anything for that one. In the current implementation, the power balance snapshot for that user will remain empty forever. We must identify when no balance is returned for an address and fill it with zero!
