Errors thrown in fail handler don't show stack trace or code frame

[chrisbreiding]

Current behavior:

If there's a failing expectation or exception in a fail handler, the error does not show the stack trace or a code frame with links to the calling code.

Desired behavior:

Such errors should display the stack trace and a code frame pointing to the call site.

Test code to reproduce

it('throws error in fail handler', () => {
  cy.on('fail', () => {
    foo.bar() // could also be a failed assertion
  })

  cy.get('#does-not-exist', { timeout: 1 })
})
