Damien Elmes 82a54c780f catch invalid temp folder and other tweaks
- tweak sync code so that a failure in loading the collection
  won't leave the app with an unopen collection
- don't show corrupt collection message when the error is not
  a db error
- catch the temp folder issue when loading the collection. i suspect
  this was the issue that was causing some people to end up with
  an open anki instance with no collection loaded
