(mh-folder-list): Fix problem with passing in a folder and getting
nothing back. Fix problem with passing in empty string and getting the
entire filesystem (or infinite loop). Don't append slash to folder.
These fixes fix problems observed with the pick search. Thanks to
Thomas Baumann for the help (closes SF #1435381).
