fix multibuffer "is loading"

The multibuffer tells the client that we are loading, even if the
content is already cached. However, if the content is fully cached,
there will be no progress updates, and the we'll never tell the client
that we stopped loading. This CL fixes that by posting a task that
checks the loading state right after startup.
