Remove test files from the npm package! F-Secure warning

[Havunen]

koajs/body-parsers#89

The dependency chain seems to be following:

"koa-better-body": "^3.3.9",

Loads "koa-body-parsers": "tunnckocore/body-parsers#patch-1"

which seems to be hosted here:

https://github.com/tunnckoCore/body-parsers/tree/patch-1

and it contains a test file shipped in the npm package.

Note: Koa-better-body is targeting koa-body-parser 3.1.0 is that still needed could it be updated to the official v5 ?

@Havunen hey there. Sorry for that. I'm not using koa much in the recent years and i have to catch up and update them. There was a reason why i specifically used my patch, have to review the v5.
