Detecting missing information or unsupported prompt is not consistent

Input: Send 1 NFT
Expected: Unsupported goal
Actual: Could you please specify which NFT (by its contract address and token ID) you wish to transfer

Input: Send 1 ETH
Expected: Who do you want to send ETH to?
Actual 1: Sending 1 ETH to smart account
Actual 2: user_proxy keeps looping asking for the address.

Nice finds. If we could modify the user_proxy to request missing information from the user that'd be great. Just need to make sure that:

1. we aren't requesting information too often
2. we're turning this behavior off when using --non-interactive
