Ionic on iOS 11 freeze UI while fetching contacts.
The method "navigator.contacts.find" should be asynchronously, but on iOS 11 it
blocks UI until all contacts will be fetched.
Additionally, in XCode 9 console, I can see the new output about "Increasing
interest" and "Fetching in bulk 250 contacts":
