Buggy behavior on anchor points after layout

[hasanbalci]

I have noticed two problems on the behaviour of anchor points after layout, probably related to each other. The first one is:

• Create two bend/control points on an edge.
• Apply layout, this will remove bend/control points from the edge visually.
• Right-click on the edge to open the context-menu, see "Remove All Bend/Control Points" item is still visible and clicking on it produces error in the console.

The second one:

• Create a control point on an edge.
• Apply layout, this will remove the control point from the edge visually.
• Now, try to add a control point again, this produces error in the console.
• This behaviour only occurs for control points, not for bend points.

The first one is reproducible in public version as well, which means it existed before the latest breaking edge-editing release. Second one should be caused by something that happened after (or with) the release.
