Subject: [PATCH] edje - delete obj - null out freed items in structs/data

i just got a segv freeing ian invalid ptr... it SEEMS as if something
has tried to free and edje object twice... but i can't be sure as
valgrind can't catch this. it's a one-off, so ensure after free, we
NULL out things we freed to avoid this.

@fix
