Review Comment:
   `remove` might be freed in `serviceTracker_untrackTracked`. Thus it's not 
reliable to use its value, which might be reassigned to a new 
`celix_tracked_entry_t` and be added to `untrackingServices` for a second time, 
in `celix_arrayList_remove(tracker->untrackingServices, remove)`.
