issue/1899-reader-pager-illegalstate-331

Another attempt at fix #1899, this time by swallowing the IllegalStateException when restoring the pager state. I hated to resort to that, but the crash occurs within the Android source, making it hard to completely fix.

Also removed the "end fragment" from the pager which appears when you reach the last post. There was some indication that *might* be involved in the problem, plus it seemed unnecessary since the pager already has an overscroll indicator that makes it obvious when you reach the last post.
