[FIX] hr_attendance: fix checkin/checkout on iOS

To reproduce
============
- With hr_attendance installed on ios application
- click on small button (green/red) to checkin/checkout
- nothing happens

Problem
=======
the method `signInOut` is failling because `navigator.geolocation` is
not defined on iOS

Solution
========
check if `navigator.geolocation` is defined before using it
