Used by It2MeConnectFlow to clear the inputField upon a succesful connection.

If it would make the code cleaner, I would be okay with clearing the field when
the dialog is dismissed. IIRC, we didn't blank it on an unsuccessful attempt in
case it's only wrong by one digit, in which case it doesn't need to be retyped
in its entirety, but I don't think that's a significant usability concern.
