Error in cyclegan train_discriminator

[yonigottesman]

In train_discriminator, there is a confusion with the input.
For example:
fake_images = generator.predict(real_images_A)
The generator always gets real_images_A even if its a generator_B which is supposed to get real_images_B
Also later:
pred_real = discriminator(real_images_B)
but if a discriminator_A its supposed to get real_images_A

Also, like in #20 the generator is supposed to be called with training=True
