core: fix display of read marker when all buffers line are unread

The bug is when all buffer lines are unread (so "last_read_line" pointer
is NULL), and that the option weechat.look.read_marker_always_show is on.
The read marker was displayed at bottom after switch to the buffer.

Thanks to Nils Görs.
