When sorting issues and pull requests by the nearest due date, the
issues and PRs without a due date are currently sorted _descending_ by
their creation date. This seems counter intuitive to me. When sorting by
nearest due date I want to see the issues/PRs in the order they should
be worked on. For issues/PRs without a due date that order should be
first come first served rather than last come first served.
This PR now changes the ordering of issues/PRs which don't have a due
date to _ascending_ by their creation date. So that the oldest is shown
first and the newest last.
This now also makes the sort order nearest due date a true opposite to
farthest due date. At farthest due date the newest is shown first and
the oldest last.
