Subject: [PATCH] Fix issue calculating eligible inputs.

Use the new confirmed function to test whether unspent transaction
outputs are confirmed enough to be used as a possible transaction
inputs instead of the old check (which was incorrect and required an
extra confirmation).

Modified the test to require one confirmation instead of none so the
confirmed enough check actually occurs.
