[luatex] synctex fails in luatex 1.06.2

[Ulrike Fischer]

miktex has updated to luatex 1.06.2 and now synctec fails. sumatra
reports that there are no synchronisation data available. 

It still works in texlive 2017 and so I compared the two synctex
fails and imho the problem is that the link to the main tex file is
missing at the start: 

The synctex files refers to a lot positions in input 0 but the file
list starts with

Input:1:D:/MiKTeX2.9/tex/latex/base/article.cls

I added before this line 

Input:0:G:/Z-Test/./test-utf8.tex

and then synchronization worked again. Imho this is a luatex bug.

Side remark: 
The texlive synctex of luatex 1.04 starts with number 1 and not 0
Input:1:G:/Z-Test/./test-utf8.tex
This looks as if the numbering scheme has been changed and could be
the reason why the reference to file 0 is lost.
