* Tweaked a Migration to log correctly only if something is going to be done.
* Refactored Reading List Controller code into a dedicated service and cleaned up some methods that aren't needed anymore.
* Fixed a bug where adding a new item to a reading list wasn't adding it at the end.
* Fixed an issue where collection page would re-render the same covers on multiple items.
* Fixed a missing margin-top which made the page extras drawer not render correctly and hence unclosable on small screens.
* Added some timeout on manage users screen to give data time to flush.
Added a dedicated token log for account flows, in case url encoding plays a part (but from testing it doesn't).
* Reverted back to building for ES6 instead of es2020 for old Safari 12.5.5 browsers (10MB difference in build size).
