[NTG-context] bug/issue with components and preamble (Re: Euler with fallback)

The wiki page for "Project Structure" has always shown setups (via
\project ... ) going after the \startcomponent or \startproduct.  I've
edited the examples to have setups before the
\start(product|component).  If I did it wrong, let me know.
My change doesn't work, because of how components handle project files
(which also turns out to explain why I was seeing the Euler font when
you didn't).  The problem is that context doesn't generate a pdf file if
the \project line comes before the \startcomponent.  Thus, I was seeing
a pdf file from a previous version of the test file (where the font
setup came after the \startcomponent).

Here are the two test files (testproject2.tex and test6.tex):

==== testproject2.tex ============
\startproject testproject
\stopproject
==================================

(If testproject2.tex is empty, then the problem does not occur.)

========== test6.tex =============
\project testproject2
\startcomponent test

\input knuth

\placeformula\startformula
a^2 + b^2 = c^2
\stopformula

\stopcomponent
==================================

Here is the log file.  It says 'result saved in test6.pdf' but no pdf
file is actually saved.
