Add history-based completions for autojump's j command

Browse Source 
j does not have any "logical" source of completions, but it almost often
called with arguments that have been seen before (since it is used to
jump to favorite/recent directories). We can search the history for
possible completions and use those.

This is an example of the behavior mentioned in #4344 as a possible
enhancement for fish 3.0, where completions can be provided from history
if none are otherwise found.
