`clearMocks` clears mocks once and forever

[SpeCT]

You can only clear mocks once. Every "mocked" request after that will use real fetch.

describe('Auth API', () => {
  afterEach(() => {
    clearMocks()
  })

  test('GET foo', async () => {
    mock('https://example.com/', { data: { name: 'Foo' } })
    await fetch('https://example.com/')
    expect(res.status).toBe(200) // <<- OK
  })

  test('GET foo', async () => {
    mock('https://example.com/', { data: { name: 'Bar' } })
    await fetch('https://example.com/')
    expect(res.status).toBe(200) // <<- INTERNET
  })
})
