fix: Disable Smart Transactions for the new Send&Swap feature

[dan437]

Description

Disables Smart Transactions for the new Send&Swap feature, since we don't support it there yet. Support will be added in one of the upcoming releases.

Related issues

Fixes:

Manual testing steps

1. Go to the Send feature
2. Choose a different destination token, which will make the transaction type "swapAndSend"
3. Submit it. In the background Network tab you can see it's not submitted via Smart Transactions, but as a regular transaction instead
