Gets the current folder of @chooser as an URI.
See gtk_file_chooser_set_current_folder_uri().
Note that this is the folder that the file chooser is currently displaying
(e.g. "file:///home/username/Documents"), which is not the same
as the currently-selected folder if the chooser is in
%GTK_FILE_CHOOSER_ACTION_SELECT_FOLDER mode
(e.g. "file:///home/username/Documents/selected-folder/". To get the
currently-selected folder in that mode, use gtk_file_chooser_get_uri() as the
usual way to get the selection.
Return: the URI for the current folder. Free with g_free(). This
function will also return %NULL if the file chooser was unable to load the
last folder that was requested from it; for example, as would be for calling
gtk_file_chooser_set_current_folder_uri() on a nonexistent folder.
