prune --worktrees: fix expire vs worktree existence condition 

`git prune --worktrees` was pruning worktrees which were non-existent OR
expired, while it rather should prune those which are orphaned AND
expired, as git-checkout documentation describes. Fix it.

Add test 'not prune proper checkouts', which uses valid but expired
worktree.

Modify test 'not prune recent checkouts' to remove the worktree before
pruning - link in worktrees still must survive. In older form it is
useless because would pass always when the other test passes.
