`dfx` fails to deploy `.did` files for custom canisters

[vporton]

I tried the following:

1. Create a dfx.json file with

    "nns-ledger": {
      "build": "",
      "candid": "candid/nns-ledger.did",
      "remote": {
        "id": {
          "ic": "ryjl3-tyaaa-aaaaa-aaaba-cai",
          "local": "ryjl3-tyaaa-aaaaa-aaaba-cai"
        }
      },
      "type": "custom",
      "wasm": ""
    },

2. Deploy it with dfx deploy nns-ledger.

I expected to see this happen: ls .dfx/local/lsp/ryjl3-tyaaa-aaaaa-aaaba-cai.did to show the file that MS Code should pass syntax check of import ICPLedger "canister:nns-ledger";.

Instead, this happened: The file is missing and MS Code complaints.
