Fix security group race condition while listing and deleting rules

Previously, there was a race condition that could occur if one was listing
a security group which contained a rule which referenced another security
group as an additional api call is used to look up the security group's
name which is returned (rather than id) via the API. The problem occurs if
this security group is deleted in which case a 404 was raised.
This patch fixes this issue by catching the 404 and ignoring the rule as
its already deleted as there is a constraint enforced that you cannot
delete a security group if another security group has a rule that references
that security group.
