Joshua Harlow e6a04193e7 Avoid trying to copy tasks results when cloning/copying ...

It is not always safe to copy task results so instad of
trying to copy.copy them just retain the existing results
in the clone (and avoid copying any users results if
they exist).

This appeared to be causing sqlalchemy weak references to
get garbage collected prematurely in cinder.

Fixes bug 1452978
