Remove to check valid app_id for original app_id

Remove to check valid app_id for original app_id

 [Problem]
  If client application checked server_name, it was not same with the app_id of the server application.

 [Solution]
  The dbus does not support special character, so the app_id as interface was modified to valid name for dbus.
 As the result, the modified app_id was not same with original app_id of the server application.
 The interface used by dbus already has been checked before dbus function is called.
 So I remove to check valid app_id and modify it.
