Map: explicitly reload selected map on click

When clicking on a flag
 1) The QML would call MapLocationModel::setSelected() with
    fromClick = true
 2) MapLocationModel::setSelected() would emit a signal
    selectedLocationChanged()
 3) MapWidgetHelper would catch that signal and do the actual
    processing.
Other functions would call MapLocationModel::setSelected() with
fromClick = false, which would not emit the selectedLocationChanged()
signal.

Detangle this a bit by calling the selectedLocationChanged() function
directly from QML and remove the fromClick parameter.
