Cursor position changes on, for instance, auto-reload

[AndreiUlmeyda]

newsbeuter 2.9 System: Linux 4.8.11-1-ARCH (x86_64) Compiler: g++ 5.3.0 ncurses: ncurses 6.0.20161112 (compiled with 6.0) libcurl: libcurl/7.51.0 OpenSSL/1.0.2j zlib/1.2.8 libssh2/1.8.0 (compiled with 7.46.0) SQLite: 3.15.2 (compiled with 3.9.2) libxml2: compiled with 2.9.2

Steps to reproduce the issue:

1. Set up a query feed

2. Auto-reload yes, article-sort-order date-desc

3. From top to bottom, go through a number of articles either opening them or marking them as read

4. wait for auto-reload

result: read articles are hidden as expected but the cursor position is now in the middle of the list of articles instead of at the topmost unread article as before.

This makes me scroll upwards every time I come back to the newsbeuter window.

Cheers
