Fix unable to uninstall application on macOS

Update ios-device-lib where a fix for uninstalling application on macOS was not working.
Update common lib where the following fixes are applied:
* Fix `tns devices` not showing attached iOS devices.
* Do not call uninstall of application when it is not installed - this produces some confusing warnings.
