Number of tasks in a project does not update correctly

[Asher-Meachum]

Describe the bug
Planify fails to update the number of tasks a project has if a large number of tasks are added quickly.

To Reproduce
Steps to reproduce the behavior:

1. Open a project
2. Add 5 or more tasks at once

Expected behavior
The number of tasks is updated as tasks are added or removed.

Screenshots

Desktop (please complete the following information):

Additional Information
The number of tasks will update eventually, however this may be up to several hours after the tasks are created. Additionally, closing and reopening Planify will cause the tasks to update.
