ENYO-3485: bug fix regarding temp node module to make directory under temp path (defect on ubuntu)

* bug fix regarding temp node module to make directory under temp path (defect on ubuntu).
* When there is no proper global variable about temp path, temp node module assume that $HOME/tmp as a temp path, but if there is no directory at that location, it cause error when `temp.mkdir()` function is called.
