Delegate StreamActions.refresh to Session

The bulk of the `StreamActions.refresh` implementation was reaching
through the global `window.Turbo` property, which itself was reaching
through either global variables or the `Session`.

This commit moves the implementation out of the `StreamActions` and into
a new `Session.refresh(url, requestId)` method. With that change, all
property access is encapsulated within the `Session`.

To support that change, this commit also introduces the
`StreamElement.requestId` property to read the `[request-id]` attribute.
