Clear Button not visible on Borrow Transaction Modal

[0x4Graham]

Describe the bug
The "X" icon is not in the borrow transaction modal. This will come from closed change #836

To Reproduce
Steps to reproduce the behavior:

1. Go to asset
2. Select Borrow
3. Enter amount to borrow
4. No "x" button to clear the amount is visible,

Expected behavior
After entering a value, the "X" button should be visible to clear the input

@MatthewCYLau can you please investigate.

👋 @grothem @defispartan could I seek you guidance here 🙏

• Running the latest code from my local machine, I can definitely see the clear button rendering from the AssetInput component inside of the BorrowModalContent component👇
  

• Inside of AssetInput component, the clear button renders when value !== '' i.e. value is present

• The bug screenshot above is from the RepayModalContent component

• And so, I wonder if I've missed anything to how RepayModalContent component passes amount when rendering AssetInput which would result in the clear button not being rendered

Thank you! 🙏

Hey @MatthewCYLau, I didn't catch this the first time around, but if the length of the asset list is greater than 1, then the clear button won't show. You can see this if you open the repay modal, and you have more than 1 asset in your wallet that you are able to repay with.

I think another thing that should be added is to not render the IconButton if disabled is true.
