Fix network name masking network ID on delete
If a network is created with a name that matches another
network's ID, the network with that name was masking the
other network's ID.

As a result, it was not possible to remove the network
with a given ID.

This patch changes the order in which networks are
matched to be what we use for other cases;

1. Match on full ID
2. Match on full Name
3. Match on Partial ID

Before this patch:
