When loading a page that has something like "#review20" in the window location,

we had some code to expand the review box that matched. The addition of reviews

within the initial status reports and change description boxes duplicated this

code two additional times.
This change moves that responsibility into the ReviewRequestPageView. This

now just generically searches each box for a matching selector, expanding if it

finds it. This means that it's much more general, and linking to individual

comments will also expand their container.

Checked that the matching boxes were correctly expanded when loading the page

with a variety of different hash values.
