`nvim.nim` missing

[kdheepak]

When running nimble install https://github.com/jangko/nvim_client this is the tree structure in the pkgs folder:

$ tree
.
├── nimblemeta.json
├── nvim_client
│  ├── nvim_batch.nim
│  ├── nvim_buffer.nim
│  ├── nvim_client.nim
│  ├── nvim_rpc.nim
│  ├── nvim_tabpage.nim
│  ├── nvim_transport.nim
│  └── nvim_window.nim
└── nvim_client.nimble

It appears that the root nvim.nim is not installed.
