Bugfix: the end of a reorged chain is invalid when connect fails

Browse source 
Introduced in 4e0eed88ac

When an invalid block is found during a reorg, we know the last of the blocks in
the was-to-be-connected chain is invalid, but not necessarily the first. As
vpIndexToConnect is ordered in decreasing height, the end of the reorg is the
front of the vector, and not the back.

This only affected the warning system.
