Random color jittering when testing on i-frame.

Lines 151 to 158 in 4f0857a

	if self._representation == 'iframe':
	img = color_aug(img)
	# BGR to RGB. (PyTorch uses RGB according to doc.)
	img = img[..., ::-1]
	frames.append(img)

When creating val_dataloader, is_train is set as False. But color jittering is still enabled. This may end up with inconsistent test results.
