autotest: Tolerate no IP address in interface.py
network_WiFi_DisconnectClearsIP expects that Interface will return None
when asked for an IP address on an interface that has None. This was
broken when netblock parsing was refactored to add validation logic.
BUG=chromium:433621
TEST=network_WiFi_DisconnectClearsIP now passes.
