SAML IdP attribute mappers should work with profile attributes even when the user profile mode is set to dynamic

The out of the box SAML IdP Attribute Mapper implementation does not map profile attributes when the user profile mode has been configured to Dynamic or Dynamic with Alias mode. Since the point of the Dynamic profile mode is to ensure that a profile gets successfully created at the time of the authentication, it would perfectly reasonable for the SAML AttributeMapper to just simply map the attributes coming from the freshly created user account (or even from the old account that was previously dynamically created).
