copy(adjoint(p::NFFTPlan)) not working

[JakobAsslaender]

Hi, the copy function does not seem to work for adjoint(p):

julia> using NFFT

julia> p = NFFT.NFFTPlan(rand(3,100) .- 1/2, (128,128,128))
NFFTPlan with 100 sampling points for an input array of size(128, 128, 128) and an output array of size(100,) with dims 1:3

julia> pa = adjoint(p);

julia> pa2 = copy(pa)

Thanks, fixed.
