Revert "Delaying article additions has no effect on ordering - remove it"

This partially reverts commit 2a20c05b9e6ba987fdf993feee9367f23ac6b8e2.

It turns out that reading list somehow remembers item ordering even if
the item is deleted and then added again. So the delay helps, but I didn't
notice that.
Do nut update version automatically
Move require()s to the function where the module is needed
