Update tcar.conf file.
    
    - Previously, the value of TCAR_WORKDIR inside tcar.conf file was
      using a trailing slash. This made symbolic link construction to
      duplicate the slash character near the concatenation (e.g.,
      /tmp/tcar-workplace//Webenv/Final).  This update changes tcar.conf
      file to remove the trailing slash from TCAR_WORKDIR variable's
      value. Now, symbolic links are created without duplicating the slash
      character near the concatenation (e.g.,
      /tmp/tcar-workplace/Webenv/Final).
