test: add test for all models using chai & mocha

[AmanNegi]

Description

Currently, tests are written for src/models/cart.js and src/models/comment.js. Further we require to create tests for other models. Which are namely:

1. src/models/user.js : User Model
2. src/models/millet_item.js: Millet Item Model

For reference you can see the tests written for models under /src/tests. Feel free to query about any doubts.
