CompareToSlice panics when actual slice has fewer elements than the table

[rdumont]

For instance, given the following step definition:

func (s *Steps) ThenTheReturnedErrorsShouldBe(errorsTbl *godog.Table) error {
	actualResponse := []*struct {
		Code        int
		Description string
	}{
		{Code: 123, Description: "Only one error"}, // <-- Only one element here
	}

	if err := assitdog.NewDefault().CompareToSlice(actualResponse, errorsTbl); err != nil {
		return fmt.Errorf("return errors are different from expected: %v", err)
	}

	return nil
}

And the following step in a scenario:

  Then the returned errors should be
    | Code | Description  |
    | 123  | First error  |
    | 456  | Second error |

I would expect to see an error stating that the number of elements is different. However, I got a panic like the following:

panic: reflect: slice index out of range
