Tony Garnock-Jones 97cfb19852 Move stop continuation *before* a stopping facet's assertions are retracted. 
This is a kind of ad-hocish response to an interesting problem. In
previous Syndicates, assertion changes were gathered into *patches*
which *netted out* intra-turn changes. In this implementation, each
change is relayed unchanged, so there is *no netting* going on. The
closest we get is a convention that when things are being replaced,
incoming assertions should be made before outgoing ones are retracted,
so that the kind of glitch that's seen is a double-up of records,
rather than a brief window where no records are present.

So here, by moving the stop continuation into an onStop for the
stopping facet (that nonetheless *executes* in that facet's parent's
context), we allow the following pattern to run without problem
glitching:

    react {
      assert Something(1);
      stop on asserted Condition() => react {
        assert Something(2);
      }
    }

Observers like this...

    during Something(_) => { // **A**
      ...
      during Something($specific) => { // **B**
      }
    }

will see

    + Something(1)
    + Something(2)
    - Something(1)

rather than what they saw before this change,

    + Something(1)
    - Something(1)
    + Something(2)

The consequence is that the line marked **A** above will *remain
active* after this change, with the facet at **B** being replaced,
rather than briefly tearing down the **A** facet when `- Something(1)`
and then creating a fresh one when `+ Something(2)`.

This came up in flappy bird, where I had

    react {
        at mainDs {
            assert ui.html('#board-area', template`<h1 class="score">${score.value}</h1>`);
        }
        at gameDs {
            stop on asserted GameOver() => react {
                at mainDs {
                    assert ui.html(
                        '#board-area',
                        template`<h1 class="score">${score.value}<br/>GAME OVER</h1>`);
                }
            }
        }
    }

which, in combination with the particular implementation of index.ts
in the html package, caused the UIFragment responder to get confused
and to not show the GAME OVER message - the previous score message was
removed, but the new one wasn't manifested in the DOM. Changing the
last `ui.html` above to `ui.context('foo').html` caused the problem to
go away (by making it effectively two unrelated fragments, rather than
a replacement of the content of a single fragment).

Tony Garnock-Jones e806f4b042 Partial repair for a deep problem with VisibilityRestriction. 
This change makes `during` work "atomically" across a communications
delay, by ensuring that a retracted assertion matching the `during`'s
pattern triggers the "stop on" clause in the expansion of the
`during`.

Some discussion of the change exists in the Journal and in my
notebook.
