* Lots of cleanup on the warnings in the solution. Deprecated IsLastWriteLessThan and made a new method HasFileBeenModifiedSince.
* Added some tests for the new extension method.
* Changed filter import to use correct import
* Scan Series now uses Refresh Metadata for Series, rather than library one.
* Fixed an issue where cover generation wasn't properly taking forced update into consideration. Removed a case of cover generation for no reason.
* Fixed series downloads not triggering backend call
