Fix a hang on iOS 10.3.x

[qmfrederik]

On iOS 10.3, you don't receive a message with status Complete when installing an app. This means ideviceinstaller will just hang once installation has completed.

You do get a status message where the CFBundleIdentifier is echo'd back, and you can use that to determine installation has completed.

#70 fixed the segfaults but not the underlying issue. There's a comment (https://github.com/libimobiledevice/ideviceinstaller/issues/70#issuecomment-302186271) indicating that the actual bug may be in notification_proxy, that may be a better option.

Should be fixed already.
