Use with multiple wrappers

```julia
using CuArrays
CuArrays.allowscalar(false)
cu(reshape(cu(randn(2,2))', 1,4)) # fails at displaying
CuArray(reshape(cu(randn(2,2))', 1,4)) # fails at the outermost call to CuArray
```

I hit this error all the time while backpropagating using Tracker, not sure which adjoint definition causes this error though.

Both the adjoint and the reshape are required for the error to appear, either one of them by themselves works alright.

Run the Julia 1.3 reproduction with CuArrays.allowscalar(false), then isolate the interaction between the adjoint and reshape cases, since each works alone. Trace the outer CuArray and display failures across the multiple-wrapper paths; done means the specific failing wrapper interaction is identified and reproducible.
