This commit ensures that new views are rendered for the first time. This fixes
a panic that could be reproduced by dropping the `ThemeSelector` and opening
the file finder during the same update.

This eliminates a whole class of errors where the `ChildView` could
be referring to a view that doesn't exist anymore. That probably still
indicates that there's an underlying bug, but at least we won't panic.

This commits adds the beginnings of an application state facility as a non-static place to store the most recently-activated search for each project.
I also store workspace items by descending order of their entity id so that we always fetch the newest item of a given type when calling `Workspace::item_of_type`.
