GHC 7.8.2 calls resetSignalHandlers even when --install-signal-handlers=no is specified. On windows this results in the call to SetConsoleCtrlHandler failing.

The attached patch only calls resetSignalHandlers when there are signal handlers to remove (it mirrors the logic used when installing the handlers).
