All variables from process are injected into a task function that takes in no parameters

[DanielEidlin]

Describe the bug
When you create a function that doesn't take any parameters in its signature, all the variables from the process scope are passed into it.
The workaround I used to solve this is to take in *args, **kwargs inside the task function signature.

To Reproduce
Steps to reproduce the behavior:

1. Create a task function that takes in no parameters.
2. Run a process which uses that task in it.
3. Code crashes from an unexpected parameters error.

Expected behavior
No variables should be injected and the function should complete normally.

Desktop (please complete the following information):

• OS: Windows 10
• Version 3.0.4
