Do not suggest @types installation for relative path with extension in node_modules

[weswigham]

TypeScript Version: 2.7.0-dev.201xxxxx

Code

import discord_js_original_js = require("./node_modules/discord.js/src/index.js");

Expected behavior:
Ideally no error if the file is loaded, or

index.ts(3,41): error TS7016: Could not find a declaration file for module './node_modules/discord.js/src/index.js'. 'E:/Github/TypeScript/tests/cases/user/discord.js/node_modules/discord.js/src/index.js' implicitly has an 'any' type.

If it's not found.

Actual behavior:
The above, plus:

  Try `npm install @types/./node_modules/discord.js/src/index.js` if it exists or add a new declaration (.d.ts) file containing `declare module './node_modules/discord.js/src/index.js';`

Both npm install @types/./node_modules/discord.js/src/index.js and declare module './node_modules/discord.js/src/index.js'; are nonfunctional nonsense and aught not to be suggested.

I make index.ts:

import discord_js_original_js = require("./node_modules/discord.js/src/index.js");

And build with tsc index.ts shows:

index.ts(1,41): error TS2307: Cannot find module './node_modules/discord.js/src/index.js'.

without and even with --noImplicitAny.

typescript version: Version 2.7.0-dev.20180111.

@xiongmao86 This is reproducible if you have discord.js installed.

package.json

  "dependencies": {
    "discord.js": "^11.2.1"
  }

TS will look for the types after finding the file and that's when you see the error described.

reproducible with

"dependencies": {
  "discord.js": "^11.2.1"
}

and npm install and tsc -noImplicitAny index.ts.
Trying to figure out how to change now.
