Clicking/Dragging mouse on a built street crashes the game

[jlga]

When building a road, after it has finished, if you click/drag on a road the game crashes.

Error message:
thread 'main' panicked at 'called Option::unwrap() on a `None` value', ../src/libcore\option.rs:323
note: Run with RUST_BACKTRACE=1 for a backtrace.
Simulation Panic!
"called Option::unwrap() on a None value"
