fix casing in variable name (#5778)

The attribute movedValue is misspelled with an uppercase V, this leads
to errors when printing token values:

```
$ python3 runaddon.py test.py test.c.dump 
Checking test.c.dump...
Checking test.c.dump, config ...
line 2 str=""lala\n""
Traceback (most recent call last):
