The precomplete file in en-US Windows installer is incorrect

In projects/tor-browser/build, we regenerate the precomplete file for the en-US bundle, in the $PKG_DIR/Browser directory:

cp -a ${TB_STAGE_DIR} $distdir/$PKG_DIR

[% IF c("var/windows") %]
  TBDIR="$distdir/$PKG_DIR/Tor Browser/Browser"
[% ELSIF c("var/osx") %]
  TBDIR="$distdir/$PKG_DIR/Tor Browser.app"
[% ELSE %]
  TBDIR="$distdir/$PKG_DIR/Browser"
[% END %]

pushd "$TBDIR[% IF c("var/osx") %]/Contents/Resources/[% END %]"
rm -f precomplete
python $MARTOOLS/createprecomplete.py
popd

However we generate the installer from the ${TB_STAGE_DIR} directory, which does not have the updated precomplete file:

[% ELSIF c("var/windows") %]
  find "${TB_STAGE_DIR}" -exec [% c("var/touch") %] {} \;
  pushd "${TB_STAGE_DIR}"
  makensis torbrowser.nsi
  # Working around NSIS braindamage
  mv torbrowser-install.exe torbrowser-install-tmp.exe
  python $rootdir/pe_checksum_fix.py
  mv torbrowser-install-tmp2.exe torbrowser-install.exe
  rm torbrowser-install-tmp.exe
  mv torbrowser-install.exe $OUTDIR/torbrowser-install[% IF c("var/windows-x86_64") %]-win64[% END %]-[% c("var/torbrowser_version") %]_${PKG_LOCALE}.exe
  popd
[% END %]
rm -rf $distdir/${PKG_DIR}

The mar files are generated using the $TBDIR directory, so they are using the correct precomplete file. The installer for the other locales are also generated in the correct directory, so the wrong precomplete file is only included in the en-US installer.
