Refactor to use `model` instead of `record` as argument in Action Cable
Refactor to use `model` instead of `record` as argument in Action Cable

We refer to `model` elsewhere in Action Cable's  implementation, so use
the same in `stream_or_reject_for` as well to keep the consistency.

Simplify the docs for the method to remove the usage "intention"
(that's not up to us) and mention it rejects the "subscription", not
the "connection".
