Mindmap should consistently display the line when creating child node, and when moving a node to another position

[LAlexMHllc]

Screenshot Example when the line displays for a second when creating child node. The line should consistently be displayed as the user drags to the child node position.

Screenshot Example when the line never displayed until after the child node was created

Line should move with node during drag n drop

Line displayed during new node function - DONE

Drag n drop node still needs work. Sometimes the dragged node disappears. Had to reload.
