Record history entry when moving a component to a different position

[FedericoBonel]

Closes #1629

Description

This PR fixes an issue where moving components to different positions on the page was not recording a history entry.

NOTE: This PR doesn't fix issue #1617, which means dragging a component with Rich Text around the page will still create history entries.

Changes made

• The drag-and-drop context now checks whether the location where a component is dropped is the same as the one it was dragged from before dispatching a new item selector. This determines whether a history entry should be recorded.

How to test

Verify new history entries on movements to new locations

1. Navigate to the demo.
2. Drag and drop a component to a different location.
3. Verify that the history includes an entry.

Verify no history entry on movements to the same location

1. Navigate to the demo.
2. Drag a component and drop it in the same location it was dragged from.
3. Verify that the history is empty.
