Navigator tests pass even if the destination Activity changes

Regarding `NavigatorTest`:

```kotlin
@Test fun `should forward user to movies screen`() {
whenever(authenticator.userLoggedIn()).thenReturn(true)

navigator.showMain(activityContext())

verify(authenticator).userLoggedIn()
RouteActivity::class shouldNavigateTo MoviesActivity::class
}
```

if you switch `MoviesActivity` with `LoginActivity` the test still passes
