problem with object_before_set

[GoogleCodeExporter]

If I update the Cc list for a component, it triggers the object_before_set 
function which tries to re-create an "Assignee" from the default assignee.
As this object already exist, it makes the function fail and report a double 
entry in the database.

The same problem occurs if I want to change the default assignee through this 
form to be another member of the assignee list, as the object already exist...

Attached is a quick and dirty fix to test 'newowner' is not already defined in 
the Assignee list and is different from 'oldowner'. In this case there is no 
need to create the Assignee object.
