fix: send revalidation not executed when going back and forth

[NeOMakinG]

Description

If you first validate a send amount, then hit the back button, then directly go back to the amount screen, the validation is not executed anymore, so you can go further and finally fail at TX sending time because you don't have enough fee asset amount:

Testing

See the jam in the description:

• Use any non-fee asset, using an account where you don't have any fee assets (ex: 1 USDT but 0 POL)
• Go to any send modal using the asset you have, go to the amount view and hit the max button, you should see the red button with "You don't have enough funds" message
• Hit back button, directly hit the next button and see the blue button, you can go further but you don't have any fee assets

Nice catch, 100% related to the issue too, fixed 3 bugs on the send feature in one day seems like a good ratio 😆

Fixed in 379c1ce
