export: Fetch stream data only for stream recipients.
export: Fetch stream data only for stream recipients.

Fetch stream data only for stream recipients, instead of
getting streams via realm_id.

(This change is kind of moot for now, since our stream recipients
include all possible stream recipients in the realm, but this
sets us up for when we start restricting users that we export
within the realm.)
