Ben Hymers 222fa1ee6f Fix possible out of bounds array access in Detour closest point functions
These were reported by Coverity Scan. They're extremely unlikely but still
possible - if all edges of a poly are FLT_MAX or further away from the
input point, a negative index may be used to access the verts array of a
poly.

The fix is to arbitrarily pick the first edge as the closest in case all
are tied as being very far away.
