manage.py index fails on deletion of a model with multiple indexers

When a model has multiple indexers defined on it, and an object of that model 
is deleted, running 'manage.py index' fails with an underlying exception of 
"AssertionError: Change object can't be deleted because its id attribute is set 
to None."

This is because the change.delete() line is wrongly placed inside the 'for 
indexer in indexers' loop, meaning that it attempts to delete the change once 
per indexer.

Patch (with unit test) attached.
