[gnome-software/gnome-3-22] Fix use of freed memory.

[Robert Ancell <rancell src gnome org>]

commit de57116160e09ac250d04d972fbbf367da663c15
Author: Robert Ancell <robert ancell canonical com>

    Fix use of freed memory.
    
    The change in 1350bcf fixed the containers (and possibly some of the contents)
    being leaked, but didn't then copy the contents into their new containers.
