Description:
HMI responds with SUCCESS resultCode instead of WARNINGS to AddCommand request with SecondaryImage in case isTemplate=true and image type is not .png

Occurrence: 10/10

Preconditions:

1. SDL and HMI are started
2. The mobile app is registered and activated
3. .jpg image is added successfully using PutFile RPC

Steps to reproduce:

1. Mobile app requests AddCommand("SecondaryImage" ={ "value": <name>.jpg, "isTemplate" = true, "imageType" = "DYNAMIC" }, ... )

Expected behavior:
HMI receives UI.AddCommand("SecondaryImage" = { "value": <name>.jpg, "isTemplate" = true, "imageType" = "DYNAMIC" }) request and responds with WARNINGS result code

Observed behavior:
HMI responds with SUCCESS result code to UI.AddCommand request with the image not supported as a template
