Fix msal-react SSR hydration errors

[tnorling]

When attempting to use msal-react in an SSR app it results in hydration errors when a using MsalAuthenticationTemplate or useIsAuthenticated. This PR fixes this behavior by defaulting the value of useIsAuthenticated to false when inProgress is Startup (which it will always be server-side and on the first render client-side)
