Detect attempt to fetch wikibase item of an entity

While the wikidata and wikispecies families dont allow transcluded data, the current code tries to find a wikibase item for wikidata pages, which causes a warning like the following and raises an APIError exception. WARNING: API warning (wbgetentities): Unrecognized value for parameter 'sites': testwikidatawiki

This change detects whn ItemPage.fromPage is being asked to load an item for a page on a site that cant have an item, and raises WikiBaseError instead of APIError.
