Fix the root root cause of TypeError: obj is not an object

iniGetNamedStringList() was returning NULL when attempting to get the list of keys in the "root" (unnamed) section and the file is actually empty/blank. If there were *any* characters in the file, it would return an empty list (not NULL). Now, always return the empty list, even when the file is blank.
