[#1330] [Core] Fix pausing and resuming session

* The paused state of torrents is now correctly stored on shutdown if the session is paused.
 * Resume session refreshes all the torrents' state. This fixes only torrents that changed state being
   updated so queued torrents would be incorrectly displayed as paused.
