mockCall.Unset cause panic

[hieunguyen1809]

Hi team, I'm using testify to testing my method but encounter this issue (It only occur if using matchedBy arg)
When I using mock following by example but got error when using mockCall.Unset().

For people who face this issue, i use this code

	unset := func(call *mock.Call) {
		if call != nil {
			call.Parent.ExpectedCalls = []*mock.Call{}
		}
	}
	var caller *mock.Call
	unset(caller)

as temporary fix. you can try this to

Just fyi, I put short snippet which only specific method would be deleted based on @at-syot 's code

var unsetFn = func(call *mock.Call) {
	if call != nil {
		var newList []*mock.Call
		for _, c := range call.Parent.ExpectedCalls {
			if c.Method != call.Method {
				newList = append(newList, c)
			}
		}
		call.Parent.ExpectedCalls = newList
	}
}

// caller side
unsetFn(mockInstance.On("SOME_METHOD_YOU_WANT_TO_UNSET"))

Hello @gordonlee .

Could you help promote it?
