Pin the tinydb version to 3.15.1.  
The API changed in the 4.x series of tinydb.  
However, the change doesn’t affect you learning pytest.

- This is a change to `tasks_proj/setup.py`:

`install_requires=['click==7.1.2', 'tinydb==3.15.1'],`

- and again in `ch7/tasks_proj_v2/setup.py`:

`install_requires=['click==7.1.2', 'tinydb==3.15.1', 'pytest', 'pytest-mock'],`
