Drawing a way sometimes leaves 'ghost' rays on the map that aren't really there

[Bonkles]

Start a new way by clicking on a new point.

Then click on an existing way/vertex somewhere on the map.

Hit esc to finish drawing the way- the 'temporary' ray that you drew will stick on the map, but it will have no endpoint. This 'ghost' ray seems to not actually be part of the map graph, for if you refresh the page and keep your edits, the way is drawn correctly without the ghost.

For extra credit- if you connect to a vertex, then keep drawing new vertices after that, the 'history' states appear to always be correct. This is 100% a rendering bug, and not a 'the map is wrong' bug.

Fixed in alpha 3.2 release that just went live. This was a dupe of #682.
