Title: Remove Admin's swallowing of AttributeError (#16655, #18593, #18747)

During the new-admin changes, catching of AttributeError was added to the
admin. This patch removes that as it's no longer possible to add a value to
a ModelAdmin that is not available. Adding an attribute that can not be
called causes an ImproperlyConfigured exception to be raised.
