Fix last DLT problem(s) with the new backend.

A few small stuff

fixing make_node param passing for conv_grad (conv_transpose)

This was causing problems in the case of Pool, but I also fixed it elsewhere just to be sure.

Faster travis

Will re-enable when it is fixed.

Also add some missing tests (d3viz, typed_list).

Fix test when mode!=DebugMode on the GPU.
