Write backend tests for tasks

[d4vidsha]

Currently the CI is at code coverage 91% as of writing. We can increase the testing code coverage by writing tests for the backend route /tasks. Since the current implementation of the tasks route is very similar to the items route (see Swagger docs items and tasks), and since items already has the required tests, it suffices to use backend/app/tests/api/routes/test_items.py as a reference to write up a new file called test_tasks.py which will handle all the tests for the tasks route.

Hi @d4vidsha,

I’d like to work on this. Can you let me know which testing libraries are used and provide some context on the tasks? I’ll handle the rest.

Hey @SureshPradhana, I have now provided a description for this issue, let me know if you need anything else and thank you for picking this one up! I'll be writing more descriptive issues from now on also since we now have more eyes on this project 👍
