uc_domain settings must pass #default_value

I have the uc_domain module installed and was perplexed why the uc domain form settings were never getting displayed on the domain_conf_form. I tracked it down to this little one liner.

To see the bug, install uc_domain and try to save some domain-specific settings in the uc section of the form. The values actually do get saved, but then when you redisplay the for, none of the #default_value's on the elements are set.
