Allow retrying chapter loading if interrupted (#6828)

Browse Source 
Chapter loading can sometimes get interrupted, most importantly if
the corresponding fragment tries to refresh the view again.
Before, this set the chapters to an empty list, indicating that it
should not be tried again. Now, interrupted exceptions do not set
the list to be empty, so it can be retried later.
