commit 6f3824673c6b0d360dd3bbeed7aa3b6c33135aea

    make FmXGridCell more disposed-safe
    
    fixes a segfault (crash) in these conditions:
    
    * the form's AfterInsert StarBasic script does a reload() of the form
    
    * the insert happens by clicking into a cell which has
      scripts linked to the events FocusLost and FocusGained.
      The case that led to discovering this involved a ListBox whose
      RecordSource changes when focus is gained or lost.
    
    Then there was a race condition between the cell's dispose (from the
    form's reload()) and the _old_ cell's FocusLost being executed.
    NewStyleUNOScript::invoke would then call
    xControl->getModel
    with xControl being the involved cell,
    leading FmXGridCell::getModel() to call m_pColumn->getModel()
    with m_pColumn == NULL.
