Edge labels in style not rendered by QGIS without plugin

[visr]

Loading a GeoPackage directly looks the same as loading via the plugin, except for the Edge labeling. The Edge labels are set to concat("name", ' #', "edge_id"). QGIS does not show the ID for Edge, only for Node.

This is the trivial testmodel loaded outside the plugin:

And this is within the plugin:

It seems that the QGIS plugin is still setting the labeling explicitly. Ideally this code can be removed since it is part of the style. This should work since it works for Node as well.

I noticed this when reviewing #1748.
