[3.5] bpo-29931 fix __lt__ check in ipaddress.ip_interface for both v4 and v6. (GH-879) (#2218)
the original logic was just comparing the network address
but this is wrong because if the network address is equal then
we need to compare the ip address for breaking the tie
add more ip_interface comparison tests.
(cherry picked from commit 7bd8d3e794782582a4ad1c9749424fff86802c3e)
