stream create: Avoid unnecessary val attribute.

Browse Source 
We used to put the user's email in a value, which was
redundant (we could find the value from
our parent's label) and brittle (would break
on email changes).

Now the DOM's a bit slimmer and more robust.

Also note that we now deal with user_ids, not emails,
in the call stack until we hit the "edge" and convert
to emails for the server.
