fix(developer): ci alternate installer path
fix(developer): ci alternate installer path

CI needs to build the model compiler from an alternate path because the
production build from npm can have files not in the development build.

This was causing CI errors such as:
  kmlmc.wxs(170) : error LGHT0103 : The system cannot find the file
  'C:\...\node_modules\.bin\node.ps1'.
