fix(web): small issues with the memory viewer. (#19184)

* Match fade transition timing between photo-viewer and memory-viewer.

* Fix blank page after refreshing memory page.

If the user refreshed in the browser while on the memory page, the page
would show a blank page. This was caused by skipping initialization in
afterNavigate. Fix by always initializing the memory page in
afterNavigate.
