Warewolf test framework fails to remove output parameters from existing test cases

The warewolf test framework fails to remove output parameters from existing test cases when changes are made to the workflow. For example, if a workflow has 2 input parameters and 2 output parameters, and several test cases are associated with it, removing one output parameter from the workflow does not automatically update the existing test cases to reflect this change.

Steps to reproduce:

1. Create a simple workflow with 2 input parameters and 2 output parameters.

2. Create a test case.

3. Open the workflow and remove one output parameter.

4. Open the test window and check the existing test case; it still shows 2 output parameters.

We have encountered this issue in different versions of warewolf.

Sometimes, the warewolf test framework also fails to update the input parameters in existing test cases when changes are made to the workflow.
