Unable to send via QR code of a valid ENS address

[plasmacorral]

Description

This came up in testing PR 5191 and at the time was confirmed to exist in production.

If from wallet view, the user taps the QR scan icon in the top right corner and scans a QR code that resolves to a .eth address, nothing happens and the user is returned to wallet view with no error or indication of their failed attempt.

If the user taps "send" from drawer, wallet view, or asset details then taps the QR scan icon within the To: field, and scans a QR code that resolves to a valid ENS address, the following error is presented:
"Unrecognized QR code
Sorry, this QR code is not associated with an account address or a contract address"

This has security implications for users and creates a risk that the user could experience funds loss by sending assets to an incorrect address if they are forced to enter the ENS name through the keyboard.

Technical Details

• ENS name represented as a QR code is not recognized as a valid address on either iOS or Android v5.12.1 build 1028
