Fixed validation error when credentials_profile_name, or region_name is not passed (#7629)

Browse Source 
## Summary
This PR corrects the checks for credentials_profile_name, and
region_name attributes. This was causing validation exceptions when
either of these values were missing during creation of the retriever
class.

Fixes #7571
