### Describe the problem When calling `start` on `WebAuthProvider` builders with an application context, the android system throws the exception ``` Android.Util.AndroidRuntimeException: Calling startActivity() from outside of an Activity context requires the FLAG_ACTIVITY_NEW_TASK flag ``` This makes it hard to use the provider to another class where we're injecting the application scope via Koin. It means we end up having to pass contexts around and affects testing. ### What was the expected behavior? Expected to be able to start the universal login/logout flow (i.e. open the browser window) using the Application context ### Reproduction  - Create an application - Do the following: ``` WebAuthProvider .login(auth0) .withScheme(scheme) .withScope("openid profile email") .start( context, object : Callback<Credentials, AuthenticationException> { override fun onFailure(error: AuthenticationException) { continuation.resumeWithException(error) } override fun onSuccess(result: Credentials) { continuation.resume(result) } } ) ``` Where context is an instance of Application ### Environment  Auth0 Android Lib: 2.2.0 Kotlin 1.5 Android (v21+)
