Improve fix for bug 3305

* src/LaTeX.C
	(insertIfExists): Instead of catching all fs exceptions, test for a
	valid filename before constructing a fs::path. This gets rid of the
	exceptions because of invalid names, but does still allow other
	expcetions to be thrown (e.g. because of file system problems).
	(handleFoundFile): ditto
