Title: Fix exception bubbling up

This addresses the exception @tonyarnold mentioned in #46

```
/Users/tonyarnold/Documents/Open Source Projects/Specta/test/UnexpectedExceptionTest.m:0: error: -[_UnexpectedExceptionTestSpec group_example_1] : MyException: Oh Noes! %@
```

I did a bisect and tracked it down to 6e140532ede4557e5c01bab90d1856c6430ef087.

If I understand it correctly, if `shouldRaiseException` is not set back to `NO`, the `_UnexpectedExceptionTest` spec group is eventually executed again outside of `-testUnexpectedExceptionHandling` where the exception will then bubble up. This changeset addresses that.
