Stop erroring on unsupported log types.

There are certain log types which appeared after the UCP migration
(mostly logs from Gamepedia-specific extensions) and these messages
were flooding our logs. Errors related to these logs should no longer
appear, and an issue will be made to support these log types.

In addition to that, the part of the code that handles situations where
UCP was not relaying a wiki URL has been removed, as the relevant bug
has been fixed on Fandom's side.
