For some reason, this prompt now appears when the `LogInPanel` is dismissed. It seems that switching to Reanimated 2 syntax here changed something about how the iOS password manager logic works with our code. (One big plus is that in `LogInPanel`, the username and password are inputted together, instead of requiring two separate steps – cc @varun, who previously talked about this with me.)
Anyways: it makes sense to show this prompt when the user attempts a login, but not when the user goes back.
To avoid showing the prompt, we can clear the password `TextInput` before it disappears from the screen.
Depends on D12208
