Fix off-by-one error.

This resulted in the last element of the futureBag not being considered, and
hence produced slightly incorrect odds.
update test-poker-odds.sh after off-by-one-fix

commit 22555baa8972c8a85975188e65e18b5ffa5b19e4 fixed an off-by-one bug
which was causing the generation of slightly incorrect odds because the
last element of the futureBag was not being considered.  Update
test-poker-odds.sh with the new odds and add another test.
