+Bugfix: crash when checking the sync file status
+
+Sometimes a `Folder` is created for a local path that we cannot sync
+(e.g. it's not writable). This folder will not have a sync engine. If
+the engine of this `Folder` is accessed, this will lead to a crash.
+
+The fix is to check for the existence of a sync engine in the
+`Folder::canSync()` method.
