mapwidget-mobile: do not animate the first selection

Browse source 
centerOnLocationHard() is added in MapPage.qml so that
on `firstRun` the map is hard panned to the desired location
without animation.

This affects the selection of a new "Dive details" -> "Map it" or
when opening a GPS location in the map.

The idea behind this change is to avoid starting the map animation
from an arbitrary location such as [0,0] or London. Also, to not
start the map zoomed out completely and then zoom in on a selected
dive.

For this change to work, add the helper getCoordinatesForUUID()
to qmlmapwidgethelper.cpp/.h and use it to obtain the
QGeoCoordinates for a dive site UUID.
