[core] keep tiles renderable even if a subsequent error occurs
Since 9a9408e8111bcdcd0fcb9a93112d61ab8fce0601, we marked tiles as non-renderable if an error occured. This lead to situations where a tile was loaded + parsed successfully, then a revalidation attempt occured (e.g. because the resource was stale) which failed. In this case, we used to mark the tile as non-renderable although we could've used the perfectly parsed (stale) resource.
