apply list() around weakkeydictionary iteration

Fixed an issue where clearing of mappers during things like test suite
teardowns could cause a "dictionary changed size" warning during garbage
collection, due to iteration of a weak-referencing dictionary. A ``list()``
has been applied to prevent concurrent GC from affecting this operation.

Fixes: #6771
Change-Id: I3e1d67e978b2726a282d8b327457f2d4b239a0c6
