Using got.post with both body and cache options causes an exception

[coreyfarrell]

Describe the bug

Using got.post with both body and cache options causes an exception.

• Node.js version: 13.6.0
• OS & version: Fedora 30
• got version: 10.2.2

Actual behavior

GotError: Cannot read property 'on' of undefined
    at onError (/usr/src/npm/failures/got-test/node_modules/got/dist/source/request-as-event-emitter.js:137:29)
    at EventEmitter.handleRequest (/usr/src/npm/failures/got-test/node_modules/got/dist/source/request-as-event-emitter.js:170:17)

    at Object.onceWrapper (events.js:428:26)
    at EventEmitter.emit (events.js:321:20) {
  name: 'RequestError'
}

Expected behavior

No exception. Unsure if options.cache should do anything in this case or be ignored. For my own use that does not matter as the server I'm really working with never provides cachable responses to POST requests. Really the goal for me is to be able to use a shared "base options" object and not have to censor the cache option when performing posts.

Code to reproduce

#!/usr/bin/env node
'use strict';
const got = require('got');

async function main() {
	await got.post('https://httpbin.org/post', {
		body: '',
		cache: new Map()
	});
}

main().catch(error => {
	console.error(error);
	process.exit(1);
});

Checklist

• I have read the documentation.
• I have tried my code with the latest version of Node.js and Got.
