[wikia] setting default domain should have a check to see that it is a URL and not a name

Attempted to use wikiaset to set starwars as the default domain. Then attempted to search for something in this case han solo and broke the cog

The above exception was the direct cause of the following exception:

Nevermind, didn't see that the default wikia site needed to be the url not the name, sorry

I should probably make something as to avoid this problem so I'll reopen this issue and rename it
