[AMSDK-11761] Fix delegate of non iam

[cdhoffmann]

Description

Assurance uses FullScreenMessage to display the pin code screen. If a user sets up the messaging delegate, the RCTAEPMessaging implementation of the messaging delegate's shouldShowMessage was returning false because the fullscreen message for the pin screen is not technically a "message" as in, it does not have a parent message. This was causing the pin screen to not show whenever the messaging delegate was set.
