Update content of ResourceNotFound/ResourceAlreadyExists message

According to Redfish Base Message Registry definition [1], the first
argument of ResourceNotFound and ResourceAlreadyExists is the schema
name of the resource. This patch changes the first argument to non-
versioned schema name treewide.

Tested:
Verified the error message matches the definition, and Redfish Service
Validator passed.
