Fix DCR PUT request not updating application role audience

[Thumimku]

This PR fixes an issue in the DCR PUT implementation where the application role audience value was not persisted to the database.

Changes

• Added logic to store the application role audience during DCR updates.
• Earlier if the client name is not is the request the SP is not updated, thats not correct, hence moving the update SP section outside the if block.
• Improved unit tests to assert the application role audience update.
