Fix: The last line of the text overlaps with the text-editor's border/edge

This issue appears when ellipsis with start position is used with a large font.

textEditor.SetProperty(TextEditor::Property::POINT_SIZE, 25);
textEditor.SetProperty(Dali::Toolkit::DevelTextEditor::Property::ELLIPSIS, true);
textEditor.SetProperty(Dali::Toolkit::DevelTextEditor::Property::ELLIPSIS_POSITION, Dali::Toolkit::DevelText::EllipsisPosition::START);

Solution: Fixed early exit of loop that shift lines to up if ellipsis and multi lines and set ellipses of first line to true.
