When disconnecting Stripe via the stripe connect modal, we were not resetting the `stripeConnectIntegrationToken` which is used by backend to calculate properties of `stripe_connect_*` settings. This resulted in `stripe_connect_*` properties being retained in settings even after Stripe is disconnected as we keep passing the old integration token to settings API which overrides all connect settings. This change resets the stripe integration token to empty again so as its not using the old value even after modal is closed or disconnected.

- updated `<GhFullscreenModal>` to pass `@modifier` and `@updateModifier` through to child modal components so they can adjust their own classes
- added an `updateSuccessModifier()` action to `<ModalStripeConnect>` to set the modal size when first opening and on `@onConnected/Disconnected` actions passed to the `<GhMembersPaymentsSetting>` component
- updated `<GhMembersPaymentsSetting>` to call passed in `onConnected/Disconnected` actions when connection or disconnection is finalised
