Bug counts on project show and index

We might need (and want) to switch the bug url to something like `https://api-dev.bugzilla.mozilla.org/latest/bug?include_fields=id,assigned_to,whiteboard,status,resolution,summary,flags,ref,product,last_change_time,creation_time,depends_on,blocks&bug_id=1014570` to get the set of fields we actually want.
