Improvements for the reset command to deal with empty current alias dir correctly

#2772

I think I finally made out this crap...

What's wrong with reset command, that you need this one?

I would also suggest adding this feature to the reset command.
Get the last version directory (simply order by modified date) and recreate the current directory link.

@Ash258 well, didn't notice that

ok, it seems lacking of steps of re-linking persist files/dirs; sorry, im wrong.. and another problem is:

$version = current_version $app $global

in the reset command uses function current_version in lib\versions.ps1, sorts $appdir's version dirs by name. So I should modify it to exclude empty dirs? or... er, as what @r15ch13 suggest? (but why current dir would be modified earlier than others, I see what has been reset its current is re-linked)

Ah, ignore my comment. Didn't think this through.
current_version returns the correct version. No need to order the version directories. 😄
