Reports did not show currently, because widget configs in containers with ByDimension layout have modified categories/subcategories.

They thus did not show up under the right category (the category of the widget container). Fixed by using the right category
in getWidgetMetadata (but not getPagesMetadata).

I did not check specifically but would presume getUsers will only return max 100 users here. Ideally we would instead have a method to directly get the number of users count which would be much faster... For some Piwik installations loading this page might take a wee bit longer.
