notmuch new: Fix deletion support to recurse on removed directories.

Browse source 
Previously, when notmuch detected that a directory had been deleted it
was only removing files immediately in that directory. We now
correctly recurse to also remove any directories (and files, etc.)
within sub-directories, etc.
