fix: do not disconnect and connect when the accessToken is changed (#969)

## Description

1. When the `accessToken` is changed, `disconnect` and `connect` are
called again.
2. If the customer controls the `accessToken`, the session_key refresh
performed by the SDK is canceled(API request cancel) due to the
`disconnect` triggered in (1).
3. Even if the `accessToken` has already expired, it is refreshed by the
SDK(**SessionHandler**). Therefore, UIKit does not need to rely on this
value to handle the connect logic.
