Fix osrm-contract, tests, on Windows

As part of graph contraction, node renumbering leads to
in-place permuting of graph state, including boolean vector elements.

std::vector<bool> returns proxy objects when referencing individual
bits. To correctly swap bool elements using MSVC, we need to explicitly
apply std::vector<bool>::swap.

Making this change fixes osrm-contract on Windows.

We also correct failing tests and other undefined behaviours
(mainly iterator access outside boundaries) highlighted by MSVC.
