* Added Django environment folder in exclusion

Django projects have env/ folder in which dependencies of the project like Django, Pillow, and other libraries are installed from the requirements.txt file. It would be best if this folder of dependencies is ignored from the language statistics.

* Corrected Errors

Corrected the misplaced code and put removed the start character as the environment folder may not always be in the root.

* Adding test for env folder
