Subject: [PATCH] Correctly detect initial fetch of chapters (#689)

Since the number of chapters gets converted to be index based, 1 available chapter would result in 0.

Due to this, in case a manga had exactly one chapter before updating the chapters, it was incorrectly detected as the initial fetch and the new chapters did not get automatically downloaded.
