**BUG**
Concise problem statement:
When trying to autoroute and then cancel it, then move a components, there are bugs:
1) when components are moved, ratlines are doubled: one remains at the old position, one at the new 2) the autorouter sometimes routes to the components' old positions, and sometimes to both old and new position 3) when doing so, the router completely ignores spacing, routes through pads and components, creating short circuits everywhere.
Steps to reproduce bug:
1. create any schematic and PCB
2. try to autoroute PCB, cancel it
3. try to move components around and see the ratlines are buggy, try to autoroute after moving
Results: both ratlines and the autorouter don't work
Expected results: ratlines and autorouter should work as before
