Investigate how to run FastAPI Tests with TaskIQ integrated into the stack

[devraj]

Describe the bug
FastAPI provides a nice way to test our API endpoints.

Upon integrating TaskIQ, the tests have stopped working and throw a taskiq.exceptions.SendTaskError exception. I am assuming this is because the way the tests are executed don't boot up the context that TaskIQ requires to communicate with the backend to queue the tasks.

The ticket is a reminder to investigate what needs to be changed for this to work with TaskIQ integrated.

To Reproduce
Steps to reproduce the behavior:

• Bring the stack up
• Run task dev:test

If you comment our the Task queue portion in the handlers then the tests succeed.

Expected behavior
All tests should pass
