retryTimes() generates a new snapshot on each retry

[Hypnosphi]

jest.retryTimes(3)

describe('foo', () => {
  it('works', () => {
    expect(1).toMatchSpecificSnapshot('foo.snap')
    throw new Error()
  })
})

expected: only 1 snapshot is written
actual: each retry has its own snapshot

// Jest Snapshot v1, https://goo.gl/fbAQLP

exports[`foo works 1`] = `1`;

exports[`foo works 2`] = `1`;

exports[`foo works 3`] = `1`;

exports[`foo works 4`] = `1`;
