[UPD]Fix bug when send aged statement

* Put default_parent_id to false if it is in context
because it could be use in mail.compose.message model
and create a bug saying xx id doesn't exit in model.
* The default_parent_id only exists when doing search with
the related company field; to fix this issue, check if the
context contains the default_parent_id and put it false
