Consider using `g_type_name` instead of `g_base_info_get_name` when possible

It is a better name for the .name properties (the one that gets logged in the console.) This is very helpful in debugging, particular in the early stages of the project.

The GObject.type_name produces more consistent and better names for classes and methods, unlike GI.BaseInfo.get_name, which only returns the name of the type without including the namespace info.

Another alternative would be just using namespace + name (factoring in parent types). Compare:

GObject.type_name	GI.BaseInfo.get_name	namespace + name
GtkWidget	Widget	Gtk.Widget
gtk_widget_init_template	init_template	Gtk.Widget.init_template
GObject	Object	GObject.Object
