Always reload after a successful reauth flow

[jbouwh]

Proposed change

This PR will update the helper async_update_reload_and_abort is to always reload after a successful reauth flow by default.

When the entry needs attention, this can e.g. be due to a temporary disabled account. In cased where the entry is not updated, because the credentials did not change, we still want to reload the entry as this helper promises after a successful re-auth flow. Otherwise the entry might stay in its faulty state.

For backwards compatibility, it is still possible to fall back to the old behavior by passing reload_even_if_entry_is_unchanged=False.
