How to remove the registred plugin ?

[Dakad]

I'm writing some unit test for a chrome-extension and I was testing the function that uses chrome.i18n.getMessage(). Each test passes smoothly at first but I have to skip the second test on the specific function.
.

But after testing my function by removing the skip at line 57, that happens :

According to the Wiki about Cookie plugin, I assume the registered plugin must be removed after the test in order to restore the sinon stubs.
I tried the chrome.flush() and delete chrome, both didn't work.

** ❓ Does somebody know to do this ❓ **

Unfortunatelly, there is no way to remove registered plugins.
