Fix calculation and display of eth received amounts in swaps (#9546)

* Update txMeta after postTxBalance has been retrieved

* Use gas used from txReceipt to calculate eth received

* Return null from getSwapsTokensReceivedFromTxMeta in tokenSymbol is ETH and txReceipt is missing

* Get latest txMeta before updating it with postTxBalance in case of a swaps tx in confirmTransaction

* Lint fix
