Import imports .json file over .ts file

[mauro0x52]

Not a big issue, but funny.

If I have two files, config.json and config.ts, and an import like this:
import config from './config'
it imports the config.json instead of config.ts.

This only happened with ts-node. I tried setting up resolveJsonModule = false in tsconfig.json, but still imports config.json.

With tsc, it imports config.ts normally, unless I explicitly import using import config from './config.json'.

This is just how ts-node works, see https://github.com/TypeStrong/ts-node#how-it-works for a little more info. Someone tried to add support for a hack around this in #649 which we could land. Closing in favour of #529.
