[BUG] Pressing escape when placing a river or road deselects it

[ThatRobVK]

Describe the bug
While placing a river and pressing escape, rather than just stopping placement mode, it deselects the river entirely. This is annoying when you want to place it and then edit some of its properties as you have to select it again.

To Reproduce
Steps to reproduce the behavior:

1. Place a river
2. While still in placement mode, press escape key
3. River is deselected

Expected behavior
Edit mode ends, but the river stays selected.
