Fixes for the mapviewer QtLocation example

Currently identified problems with this example are:
- the map element loses focus upon provider switch, or opening some
other page (geocoding page, for example)
  - caused by changes in the StackView. Solved by forcing the focus
    upon map change
- selecting minimap causes segfault
  - caused by dereferencing a null pointer (m_flick.m_animation)
    in qquickgeomapgesturearea.cpp
- occasional (random) crashes with "QVector index out of bound" error
- the menus show up on the wrong screen most of the time if the window
spans multiple screens (but this is a broader qtquick problem)

This patch fixes the first two issues
