FIX - Register and Login components - props.history.push undefined

[nswalters]

Register and Login components are using props.history.push but don't have access to props.

[nswalters]

In Apptrakz.js, define the routes for register and login as follows to resolve:

    <Route path="/register" render={(props) => <Register {...props} />} />

    <Route path="/login" render={(props) => <Login {...props} />} />

This will pass the props to those components. It also ensures that the useState hooks in each respective component continue to work as the components are still being rendered as functional components (resolving the Invalid Hook Call - Hooks can only be called inside the body of a function component error).
