Update tests for required field changes in SDK

Remove .orElseThrow() calls from tests where the SDK now returns
non-optional types for id and conversation_id fields:
- ContactsCreateResponse.getId() now returns String
- Conversation.getId() now returns String
- Message.getConversationId() now returns String
- Note.getId() now returns String
