Fix repr of conv layers

[angeloskath]

Before

print(nn.Conv1d(128, 128, 4, groups=128, padding=0))
Conv1d(1, 128, kernel_size=4, stride=1, padding=0, dilation=1, groups=128, bias=True)

After

print(nn.Conv1d(128, 128, 4, groups=128, padding=0))
Conv1d(128, 128, kernel_size=4, stride=1, padding=0, dilation=1, groups=128, bias=True)
