Add OwnerName to ApplicationOfferFilter

[hemanthnakkina]

Description

CreateOffer fails in finding the application offer if the controller model owner is different from the current user.
This is due to missing additional filter OwnerName for ApplicationOffers.

This PR gets the ModelOwner from model client and updates the filter to use OwnerName.
