Auth state does not update in expired state

[elfdie00475]

IMPORTANT: Before you create an issue, please take a look at our Issue Reporting Guide.

Briefly summarize your issue:

The auth state does not change after auth token is expired.
When AVS does not get the new token, the auth state will be changed from REFRESHED to EXPIRED.
Then, let the AVS get the new token. I can see that the token will be changed but the state is not changed back to REFRESHED.

What is the expected behavior?

1. The token will be updated in LWAAuthorizationAdapter
2. Auth state will be changed from EXPIRED to REFRESHED in AuthorizationManager
3. Auth state will be changed from EXPIRED to REFRESHED in SampleApp

What behavior are you observing?

1. The token will be updated in LWAAuthorizationAdapter
2. Auth state is still EXPIRED in AuthorizationManager
3. Auth state is still EXPIRED in SampleApp

Provide the steps to reproduce the issue, if applicable:

1. Start the AVS normally
2. Disconnect the network about 2 hours
3. Re-connect the network, and check the auth state in SampleApp
