Fixed

• [py_src] fixed functions in dnn that return *this.

  For this part, this original code (as in python-opencv) would case a new object to be allocated in C++ like

  TextDetectionModel_DB retval;
  retval = self.setSomeValue(...)
  return pyopencv_from(retval);

  Noticing the address of the object has changed (because it's a new one) after calling m.setBinaryThreshold.

  >>> import cv2'
  >>> m = cv2.dnn_TextDetectionModel_DB("DB_IC15_resnet18.onnx")
  >>> m
  < cv2.dnn.TextDetectionModel_DB 0x1064cf210>
  >>> m.setBinaryThreshold(0.5)
  < cv2.dnn.TextDetectionModel_DB 0x11ecda7f0>
