---------------------------------+----------------------------
ModelChoiceField gets queryset as an init argument and uses
ModelChoiceIterator for populating choices. Iterator than calls
queryset.all() which makes an unnecessary clone of QS - making its cached
data go away and issuing new database query if a queryset has been
evaluated before.
