Removes fixed_ip_get_network

Removes fixed_ip_get_network since it doesn't actually work anymore
(at some point in the past the network must have been stored along
with the network_uuid but this is no longer the case) and nothing
else uses it anyway.

Also cleans up fake db test model to remove the fake_fixed_ip_get_network
and underlying network reference which makes it closer in sync
to what is actually implemented now
