use-test rule should not allow named imports

[atabel]

I think this shouldn't be allowed:

import {test} from 'ava';

Import default should be forced:

import test from 'ava';

Ava works fine if you name-import it but some other eslint-plugin-ava rules don't work properly if you name-import ava

I can make a PR if you want

[sindresorhus]

Yes, good idea! PR welcome :)

It should also be auto-fixable.

The following should be allowed though:

import {serial as test} from 'ava';

I can't quite recall why I kept that export. Perhaps we should just remove it? See avajs/ava#1862.

We'll be removing the export. Thanks for raising this, and making the PR, @atabel!
