fix: [#6746] Move SaveAllChanges method from SetProperty to OAuthInput

[sw-joelmut]

Fixes #6746

Description

This PR moves the SaveAllChanges functionality from the SetProperty and SetProperties classes to the OAuthInput class.
Additionally, addressing the old issue (microsoft/BotFramework-Composer#9533), that introduced this change.

Specific Changes

• Removed SetProperty and SetProperties SaveAllChanges functionality, as it was causing message duplication in the Slack adapter.
• Added the SaveAllChanges functionality to the OAuthInput class, before sending the OAuthCard from the Skill to the Root to exchange the SSO token, and not loose state.

Testing

The following image shows an SSO bot working, retrieving the user's state after exchanging the token, correctly.
