Bug 19862: Turn off RoutingListAddReserves on new installations

The RoutingListAddReserves feature currently doesn't work as
expected (see bug 2894) and should be turned off for new
installations until properly fixed.

To test:
- Run the web installer
- Confirm that RoutingListAddReserves is set to "Don't place"
