fix: a token lookup that answers after the user left AddToken no longer changes the screen (closes #603)

When the contract lookup on AddToken answered, the popup always went to AddressDetail, even after the user had opened another screen. The token is still added when the network has not changed. The popup now goes to AddressDetail only while AddToken is the screen showing. It tells this from state.currentView, as Send does. The status line is cleared once the token is added, so Back onto AddToken no longer shows "Looking up token...".
