Flaky and false positive tests on EditDataModelBindings

[TomasEng]

There are several issues with the unit tests on the EditDataModelBindings component:

• In several places, the expect methods are not called, causing false positives.
  Code like expect(something).toHaveBeenCalled should be replaced by expect(something).toHaveBeenCalled(). However, this will cause at least one of the tests to fail, indicating that there is a bug, so this should also be investigated.
• The tests are flaky because of the way user events are fired. A UserEvent object should be set up first using userEvent.setup() and the events should be fired using act instead of waitFor: await act(() => user.click(element));
• The deprecated toBeCalled method needs to be replaced with toHaveBeenCalled.
