Is your feature request related to a problem? Please describe.
When selecting a feature for editing the nodes are visible even if it is not allowed to edit the geometry. This could happen if the layer is configured to allow edit attributes but not the geometry. It confuses the users when the nodes are visible, but they can not edit them.

Describe the solution you'd like
The nodes should only be visible if the user is allowed to edit the geometry.

Describe alternatives you've considered
Live with it.

Additional context
Showing the nodes was implemented in #2280
