Fix "choose icon" on profile menu items

Summary:
Ref T10054. This fix is a little rough but the "right" fix involves a ton of rewriting to `AphrontSideNavFilterView` and I don't want to open that can of worms up yet.

Specifically, the problem is:

- we build the menu in order to populate the mobile/application menu;
- as a side effect of building the menu (not rendering the menu), we initialize the menu collapse/expand behavior;
- but we never actually render the menu, so the `JX.$()` call fails.
