call this.txStateManager.setTxStatusConfirmed before async call in confirmTransaction (#9522)

* call this.txStateManager.setTxStatusConfirmed before async call in confirmTransaction in the transactions controller

* Clone txMeta before setTxStatusConfirmed in confirmTransaction

* Correctly updateTx in confirmTransaction

* Track swaps event only if it is a swap transaction
