Works as advertised for me. What version of orgmode are you using?
There has been a bug fix in that code recently.
Note, that in that example the :imagemagick flag is superfluous. It is
necessary, for instance, if you want to be able to get a inline
displayable image in png as well.
Then, the example should be
--8<---------------cut here---------------start------------->8---
#+header: :file (by-backend (html "tree.svg") (t "tree.png"))
#+header: :imagemagick
#+header: :results (by-backend (pdf "latex") (t "raw"))
#+begin_src latex
\usetikzlibrary{trees}
\begin{tikzpicture}
\node [circle, draw, fill=red!20] at (0,0) {1}
child { node [circle, draw, fill=blue!30] {2}
child { node [circle, draw, fill=green!30] {3} }
child { node [circle, draw, fill=yellow!30] {4} }};
\end{tikzpicture}
#+end_src
--8<---------------cut here---------------end--------------->8---

Tangling is not meant to produce full LaTeX files. If you want a full
and compilable LaTeX document, use the export functionality and export
to tex instead of pdf. Then, you can manually compile the tex file.
Hope that helps,
Andreas
