tdf#131634 Don't redo actions created before text edit begins.
In SdrObjEditView::SdrEndTextEdit(), pSdrUndoManager->Redo() was invoked until all the redo actions created after text edit began were converted to undo actions. Without checking, all the redo actions include the ones created before text edit began were moved to undo stack, and caused the SdrTextObj to be destroyed in SdrUndoManager::SetEndTextEditHdl when removing the undo actions and a use after release problem. The patch add GetRedoActionCountBeforeTextEdit() so the program won't invoke pSdrUndoManager->Redo() on actions created before text edit begin.
