Part: [skip ci] simplifications in primitives location dialog

- do not use a QSignalMapper if the slot doesn't take care of the emitting widget
- to set the placement only check for the base class GeoFeature, i.e. no need to step through all primitive types
- fix compiler warning of unused variable
