The new review banner worked correctly when publishing or discarding

from the banner, but the page would fail to update correctly when

publishing or discarding from the review dialog.
This fix involved changes in two places:

1. In the unified banner, we listened to the destroyed signal for the

   draft review instead of destroy. destroy is emitted too soon, and

   gets handled before the model has reset its attributes.

2. In the review dialog, when publishing, we explicitly reload the page

   at the end of the process.

Published and discarded reviews from the review dialog. Saw everything

update correctly.
