test: add addrman test for special case
if an addr matching the network requirements is only on the new table and
select is invoked with new_only = false, ensure that the code selects the new
table.
in order to test this case, we use a non deterministic addrman. this means we
cannot have more than one address in any addrman table, or risk sporadic
failures when the second address happens to conflict.
if the code chose a table at random, the test would fail 50% of the time
