fix(8667): trigger swap tx on approval tx confirmed

[Akaryatrh]

Description

When swapping a token that needs approval (and requires a 2 step swap process), it's needed for the user, when using a hardware wallet, to manually sign transactions. Currently, second modal opening is triggered when approval transaction is finished (meaning when it has been submitted). But this would end up in a situation where the first modal was not unmounted before it was asked to be mounted again. This flow was creating an issue where the user could not confirm the second transaction (as second modal was never displayed)

To mitigate this issue, we choose to wait for first transaction completion before starting the second one. This is not perfect from user POV as a long delay can happen between approval and swap txs, but as discussed with @AlexJupiter and @gantunesr it's considered as a temporary solution until we figure out a long term one.

Manual testing steps

For ease the explanation, we are using AAVE and MATIC on Polygon network and will sign txs with a Ledger account. You also need blind signing to be enabled on your Ledger device.

1. make sure AAVE token approval has been revoked here https://polygonscan.com/tokenapprovalchecker for your Ledger account
2. select swap action from actions dropdown
3. select your Ledger account
4. select AAVE token as origin token
5. type a value that you want to swap (0.0000001 is fine)
6. select MATIC token as destination token
7. get quotes (you may need to retry several times this step)
8. Swipe to swap
9. First modal should be displayed. Sign approval tx on your ledger device
10. Once approval txs is confirmed, second modal is opening. Sign swap tx on your ledger device
11. Swap should be completed
