• check if call is disconnected after clicking end button

I tried to do test case disconnect after clicking end button , but the test would always fail. I believe this a detox issue, and the issue is still open https://github.com/wix/Detox/issues/1185

No views in hierarchy found matching: (with tag value: is "<Test ID>" and view has effective visibility=VISIBLE
