- Previously, render module didn't verify whether the working
  directory was a supported working directory or not. As consequence,
  variable expansion inside configuration files at render time might
  be expanded to a value different from that expected. This update
  changes the render module to verify the workplace before render any
  content.

  The main problem solved here is the correct expansion of
  TCAR_WORKDIR variable value. If the working directory isn't
  verified, and this value isn't retrieved from the configuration file
  inside it, TCAR_WORKDIR is expanded to its default value which might
  be not the place where your working directory is really stored in.
  As consequence, automation script will try to take content from a
  place that might not exist, making the automation scripts to fail at
  some point.
