bugfix: logic when coin sold out is incorrect

[domechn]

when coin is sold out, it will not be save in db with amount and usdPrice is 0.

fix code:

// ...
	const filteredTotals = _(totals).filter(t => !_(t.wallet).startsWith("md5:")).filter(t => {
		// already handled in loadPortfolios
		if (t.usdValue === 0){
                    return true
		}
		if (t.usdValue > 1) {
		    return true
		}
		const totalWallet = md5(t.wallet)
		const lastAsset = _(lastAssets).flatten().find(a => a.symbol === t.symbol && a.wallet === totalWallet)
                // not found in last asset, which means coin has already been removed before last record
		if (!lastAsset) {
		    return false
		}
                // coin has been sold out in last time
		if (lastAsset.usdValue === 0) {
			return false
		}
		return true
	}).map(t=>({
		...t,
                // if usdValue < 1, means it has been sold out this time. update it to 0, because coin whose usdValue < 1 will be ignored before saving to database
		usdValue: t.usdValue > 1 ? t.usdValue : 0,
	})).value()
