Hannah Wolfe e060a4f811 🎨 🐛 Improve theme lib, middleware & error handling (#8145)
no issue

🎨 simplify loader - use loadOneTheme for init
- use loadOneTheme for init
- move updateThemeList to the one place that it is used
- this just reduces the surface area of the loader

🎨 Move init up to index temporarily
- need to figure out what stuff goes in here as well as loading themes
- will move it again later once I've got it figured out

🎨 Reorder & cleanup theme middleware
- move the order in blog/app.js so that theme middleware isn't called for shared assets
- add comments & cleanup in the middleware itself, for clarity

🎨 Simplify the logic in themes middleware
- Separate out config dependent on settings changing and config dependent on request
- Move blogApp.set('views') - no reason why this isn't in the theme activation method as
  it's actually simpler if it is there, we already know the active theme exists & can remove the if-guard

🎨 Improve error handling for missing theme
- ensure we display a warning
- don't have complex logic for handling errors
- move loading of an empty hbs object into the error-handler as this will support more cases

🐛 Fix assetHash clearing bug on theme switch
- asset hash wasn't correctly being set on theme switch

🎨 Remove themes.read & test loader instead
- Previously, we've simplified loader & improved error handling
- We are now able to completely remove theme.read as it's nothing more than a wrapper for package.read
- This also means we can change our tests from testing the theme reader to loader
