Closes #481

that was a tricky one, after research I found the root cause. Since default decorator always uses mock = _default_mock, when we apply double patching, we override the value of the _patcher. When standard python mock is trying to stop the patcher, it fails, since we have another object in the memory.

Keeping only single mock for all nested functions is sufficient enough. Thus, prevent from override and do clean up on the __exit__.

Should the function on line 810 only be defined when we're creating a patcher as well?

confirm, let's save some runtime on it and just return if patcher already exists
