Modify setDefaultSmsApplication API

* Introduced new logic that allows the profile owner of an
  organization-owned device (COPE PO) to set the default
  SMS application in the personal profile.
* Modified the API to be callable on the parent profile
  instance if called by the COPE PO.
* When called by the COPE PO, the package provided
  must be a system package, otherwise an IllegalArgument
  Exception is thrown.
