{Profile} Show tenant display_name for tenants without subscriptions

[jiasli]

Description
#12726, #12824 used a workaround to retrieve the missing display_name from additional_properties['displayName'].

After Azure/azure-rest-api-specs#8384 is merged and azure-mgmt-resource SDK is regenerated, this line is now (on the contrary) discarding display_name because additional_properties always exists and display_name will be overwritten with None.
