[PATCHv2 4/9] android/health: Refactor channel creation

[Andrei Emeltchenko <Andrei.Emeltchenko.news@gmail.com>]

From: Andrei Emeltchenko <andrei.emeltchenko@intel.com>

Avoid using app_id when we shall use app structure itself. Otherwise we
end up with unnecessary searches for app and problems for incoming
connections.
