Make TenantAssetController not depend on suffixed storage_path()

The only thing the controller now depends on is that FilesystemTenancyBootstrapper needs to be enabled (so basically, the same dependency as before, but before this, there was the extra "suffix_storage_path === true" dependency -- not literally, storage_path() just had to be suffixed in tenant context, otherwise, the controller would read from the central storage in tenant context).
