Avoid calling the WS core_search_get_search_areas_list after login. This is done by AddonBlockSearchForumsHandlerService.

Instead of calling it in isEnabled, we could create a component for the block (instead of using CoreBlockOnlyTitleComponent) and check in there if the block needs to be rendered or not.

Another alternative is to create a new callback in the delegate/handler to check this before rendering the block.
