Broken token image/name when a quote is refreshing

[elena-zh]

The issue happens when keep the confirm modal opened, and right in the time when a quote is 'refreshing'

Steps:

1. Connect to a wallet
2. Specify a swap order
3. Open confirm modal
4. keep it opened: wait for some quotes to refresh

AR: when a quote is 'refreshing', broken 'buy' token image appears, name is not displayed

for swap and bridge the value even can get stuck:

1. specify a swap and bridge quote
2. go to the confirm modal
3. switch to another tab in the browser
4. return back to the CoW Swap in 40 seconds --> the missing buy token info is displayed

ER: the token should be displayed
