Finally fix the stupid LocalStatus folder bug, I really hope!

Noted thie code:

    statusfolder =
    statusrepos.getfolder(remotefolder.getvisiblename().\
                                         replace(remoterepos.getsep(),
                                                 statusrepos.getsep()))

in accounts.py.  Should have been using the sep of the LocalStatus all
along.
