    tdf#153289: remove problematic assertion
    
    It is unclear what it should guarantee; but at least when ungrouping,
    SwDoc::UnGroupSelection copy-constructs a shared pointer (increasing
    the refcount), then a copy-constructed argument passed to
    lcl_CollectTextBoxesForSubGroupObj increases it once again, and then
    the assertion expectedly fails.

    tdf#148687 tdf#149173 tdf#149546 sw: fix crash with textboxes
    
    Regression from 2110597ac730fa07dbbdd603fda82b182ed27c9e
    "tdf#147485 sw: fix group shape crash using std::shared_ptr".
    
    Details:
    
    1) Using reference instead of copy assignment in SwTextBoxHelper.
    
    2) Cleanup: Unused parts of SwTextBoxHelper were removed.
    
    3) Fixing destruction of textboxes, in case when first the shape
    is removed, with clearing all textboxes from the doc and the shape
    before the pointer is released. All of this only have to be done if
    the call is not coming from the swdoc dtor, unless there will be
    double freeing.
    
    4) Missing style conversion was fixed in writerfilter.
    
    5) Don't import sections in textboxes, unless the hack of dummy
    paragraph before tables in sections will be applied and the paragraph
    with anchored objects inside will be removed with the objects;
    
    6) ConvertTextRangeToTextFrame also fixed, so embed frames in
    frames are imported from now. (Also textboxes in frames, this
    can be useful when there is a floating table having group
    textbox with nested complex content inside, or floating table
    in floating table, etc...) Note: Follow up commit will enable
    group textbox import in frames and tables.
    
    7) Import of group textboxes with complex content in header/footer
    was impossible, from now this is also supported both from DOCX and
    ODT (test included).
    
    8) Guard class for blocking unwanted recursive textbox sync
    has been introduced, and maybe some speedup with group
    textbox import has been achieved.
    
    9) The anchor sync method got a new function which avoids
    unnecessary sync when the anchor is the same.
    
    10) Sync of As_char textboxes during layout calculation caused
    crash so that has a workaround from now, for DOCX import anchor
    change and Undo. That syncs starts before the layout calculation
    so sync not needed later.
    
    11) A memory leak was found in Undo, which has been fixed.
    
    Note: layout test "testTdf147485Forcepoint" has to be limited
    to Windows and Mac builds, because font substitution
    causes crash on the Unix based systems.
