Fees are displayed when select an unsupported token

[elena-zh]

Low priority as it might be an edge case

1. Select a token to sell (supported), specify an amount to sell
2. select an unsupported token in the To field
3. change a token in the To field to a supported one
4. again, change the To token to an unsupported token in the list

AR: Price and Fee fields are displayed along with the 'Unsupported token' message

ER: Price and Fee fields are not displayed along with the 'Unsupported token' message

Besides, a message about an unknown price impact is displayed

Expected: no such a message when a token in not supported.

This is interesting.
I think we didn't use to have any data when the token was unsupported so this case was never handled.

Maybe this changed recently @anxolin @W3stside

Just to clarify: the issue is an edge one, that is why it has a low priority.
You will be able to reproduce it by following the exact steps in the description (you need to change a token pair several times).
