Doesn't parse file name when parsing a (certain) log file generated by Tectonic

[doronbehar]

Hello!

Thanks for creating this tool. I came about it after a discussion in lervag/vimtex#2703 . Basically the issue is that this file:

\documentclass{article}
\usepackage{tikz}
\usepackage{amsmath,mathtools}

\usetikzlibrary{hobby,calc}

\begin{document}

$

Hello World!

\end{document}

Makes Tectonic produce this log file:
