verifyNeverInvoked retuns false positive results

When I use this method in this way
```
$WS->verifyNeverInvoked('callFactory', ['0', 'myCalledMethod', [
'firstid' => 123,
'secondId' => 123,
'thirdId' => 124567,
'data' => [
'value' => 456
],
]]);
```
The test appeares as OK (green tick) even if the method «myCalledMethod» was called before with the same arguments

从 verifyNeverInvoked 入口点开始，使用相同的参数重现所示调用。跟踪之前的调用是如何进行比较的；完成的标准是，之前对 myCalledMethod 的相同调用被报告为失败，而不是通过。
