fix(sway): resolve destruction dependency between Ipc and SleeperThread

Browse Source 
Ipc destructor closes socket and thus wakes up SleeperThread which was
waiting for socket data in Ipc::handleEvent.
Ipc::handleEvent then proceeds with sending signal to already destroyed
object, causing heap-use-after-free Address Sanitizer error.
