Only try to send the "Exit" message if the `IPCPipeUnixSocket` object exists. If the constructor fails, then `ipc_` might remain nullptr, which would lead to a nullptr dereference in the destructor. This change also modifies the constructor so that only a valid `IPCPipeUnixSocket` object will be saved into the `ipc_` member, which avoids error messages when `IPCPipeUnixSocket::sendAsync()` is callded in the inappropriate state.
