Update PD_Classification.py. Correct test/train report assignation into their corresponding pickle files.

[Ignaci09]

Sent test and train reports into their corresponding pickle files because names of the files were swapped.

Description

The test report and train report are correctly sent into their corresponding pickles.

Motivation and Context

The test report was being sent into the training report pickle and viceversa. Now they are correctly assigned into their corresponding pickles.

How has this been tested?

I ran:
the makefile
with no errors
make clean
with no errors
pylint --rcfile=pylintrc teaspoon/teaspoon/ML/PD_Classification.py
with many errors about pylint having evolved, and the Camelcase; thus getting a low mark (0.56/10), but I just swapped a couple of names so I don't think the style has changed.
