Handle error code-tag is present in a file but file is missing in Common-template

- The if else statements throw an error when replace ejs code-tag is present	in the specific file, but the common file is also missing in the common	template - This handles the error by just replacing the replace_here tag with	an empty string, since this tag is not defined for the second render
