If an object is allocated out of the NULL context, info->parent will be NULL. Using the PTR_FROM_HEADER macro would be incorrect: it would say that ralloc_parent(ralloc_context(NULL)) == sizeof(ralloc_header).
Fixes the new "null_parent" unit test. NOTE: This is a candidate for the 7.9, 7.10, 7.11, and 8.0 branches.
