[FIX] survey: report not stored on filesystem
[FIX] Move default value in the _defaults of model and not in default_get.
Don't override the location_id if the super get_default don't retrun a value. 

Else it is impossible to set a default value, because the ir_values is always overrided with stock_location_stock as location_id
