ignore errors loading gender/mood data

For example, the site was throwing a 500 error when loading pets
belonging to frozen users. Instead, we'll now rescue that
Neopets::User::AccountDisabledError and ignore it, since it's not
*vital* that we load gender/mood data from this pet; we can still
proceed to load its customization data without it.
