HOTFIX qcore for GMHazard API tests

d.shape is something like (1, 122) so we need to check the 0 index instad.

Examples

   idx, dist = geo.closest_location(
 File "/tmp/core_api_test_20220404_0500028ic4suox/qcore/qcore/geo.py", line 59, in closest_location
   return i, d[i]
IndexError: index 93 is out of bounds for axis 0 with size 1

Made a mistake with my testing script and had the parameters the wrong way accidentally.
d.shape[0] is what it should have been
