Christian Decker 05e951d748 wire: Correct the short channel id serialization to use 3+3+2
Fixes the `short_channel_id` being serialized as 4 bytes block height,
3 bytes transaction index and 1 byte output number, to use 3+3+2 as
the spec says.

The reordering in the unit test structs is mainly to be able to still
use `eq_upto` for tests.
