network: Don't repopulate instance info cache from Neutron ports

Allocation of network interfaces for an instance can result in
corruption of the instance info cache. The result is that the cache
may contain duplicate entries for network interfaces. This can cause
instance boot failure. This bug appears to be attributable to the
combined effects of the fixes for bugs #1467581 and #1407664.

This change reverts the fix for bug #1407664, whilst keeping a
modified version of the unit test that was added with it. It also
adds a second unit test.
