dispatch: fix traceback when extension was tested with newer versions only

The "worst" extension still is the one tested with the lowest tested version
below the current version of Mercurial, but if an extension with was only
tested with newer versions, it is considered a candidate for a bad extension,
too. In this case extensions which have been tested with higher versions of
Mercurial are considered better. This allows finding the oldest extension if
ct can't be calculated correctly and therefore defaults to an empty tuple, and
it involves less changes to the comparison logic during the current code
freeze.
