Fix initialization of `@State` var

[pinarol]

Closes #

Description

This fixes a bug i detected during the Jetpack integration. Because of the way we initialize the @State variable, the token was not being set successfully. This article does a good job explaining why: https://www.swiftcraft.io/articles/how-to-initialize-state-inside-the-views-init-

From an Apple dev:

Although that will compile, @State variables in SwiftUI should not be initialized from data you pass down through the initializer; since the model is maintained outside of the view, there is no guarantee that the value will really be used. The correct thing to do is to set your initial state values inline: @State private var viewModel = SignInViewModel(...)

So I am separating the local @State token from the one passed from outside. Also removing the @State from the scope variable as well, it doesn't need to be a @State. This is not directly related with the bug, but it's the same wrong usage as well thus needs fixing.

I also rearranged the lines a bit.

Testing Steps

Go to UIKit Demo app > QE Enter email Enter token <-- important

Tap Logout if the button is present

Open the QE, verify it does NOT go through OAuth and goes directly to QE.
