(PDF guide) No table of contents

[arogachev]

What steps will reproduce the problem?

Get the latest master and generate PDF guide. Found during testing of #248. Initially thought it has something to do with these changes, but that's how it was before them. Even though pdflatex is called twice as recommended :

yii2-apidoc/templates/pdf/Makefile

Lines 4 to 6 in 43add9d

	# run pdflatex twice to generate TOC correctly
	pdflatex -halt-on-error main.tex
	pdflatex -halt-on-error main.tex

The downloadable file available on site has table of contents though.

What's expected?

PDF guide has table of contents.

What do you get instead?

PDF guide has no table of contents.
