Default Geo Location and Zoom level is ignored if one or Marker are used

[bartTC]

djangocms-googlemap==2.2.0 django-cms==3.11.5

You can set the default view of the map, in this case the center point of the USA with zoom level 5.

But as soon as you set a marker, this the center point is ignored and the map canvas spans around the marker.

If you add more marker, the map spans around all of them, the zoom level is ignored.

Is this a regression of #73?
