Fix for negative QGeoCoordinate.azimuthTo results in range ]360, 359[
QGeoCoordinate.azimuthTo() currently returns negative value
(between 0 and -1) for azimuths that should instead be in the range
between 360 and 359.
This patch should bring all returned values in the range [0, 360[
(360 excluded).
