subscribers: Rename file to stream_edit_subscribers.js.

We are going to move to this code organization for
managing streams:

    stream_create.js
        stream_create_subscribers.js
    stream_edit.js
        stream_edit_subscribers.js

The modules stream_create.js and stream_edit.js historically
manage the entire process of creating and editing stream
data (respectively).

Going forward both will delegate most of the subscriber-specific
pieces to either stream_create_subscribers or stream_edit_subscribers.

The stream_*_subscribers modules will be somewhat similar in
nature, but the way that we manage subscribers at creation time
is a bit different than how we manage subscribers at edit time.
