  Log Message:
  -----------
  lib-storage: Clear list error before mailbox_list_get_hierarchy_sep()

With ACL plugin enabled the call could have triggered dovecot-acl-list
rebuild, which in turn could have set list errors if it didn't have
permissions to all the mailboxes. This caused IMAP logins to fail.
