- better commands enabling/disabling after get/post response, fixes:

  when delete last (selected) message in mailbox content in preview 
  pane should be cleaned, when delete last (selected) message in mailbox 
  sellect-all, purge and others commands should be disabled, 
  and probably other related bugs
