Fix bug in iOSDevice detection if both physical and emulator are active

Summary:
When connecting both to an iOS emulator and physical device, the emulator devices would continuesly be replaced, and Flipper would print the warning

`Tried to replace still connected device XXX with a new instance`

Fixed the logical mistake that causes it. Not sure if this caused any actual bugs, but at least it was incorrect.
