Erroneous log error when accessing security group rules

[Gabriel Hurley]

Due to the way the APIResource class is implemented, doing a hasattr check for an attribute that's not set yet causes a log message that's actually not correct, for example the message:

Attempted to access unknown attribute "_rules" on APIResource object of type "<class 'horizon.api.nova.SecurityGroup'>" wrapping resource of type "<class 'novaclient.v1_1.security_groups.SecurityGroup'>"

can be seen in the log when accessing the instance detail page.
