* Swaps support for local testnet * Create util method for comparison of token addresses/symbols to default swaps token * Get chainId from txMeta in _trackSwapsMetrics of transaction controller * Add comment to document purpose of getTransactionGroupRecipientAddressFilter * Use isSwapsDefaultTokenSymbol in place of repeated defaultTokenSymbol comparisons in build-quote.js
