cy.mount() does not provide meaningful error message when component to mount was incorrectly imported

Current behavior

cy.mount() does not provide meaningful error message when component to mount was incorrectly imported because we are trying to determine the display name before mounting.

Desired behavior

Provide an error message similar to

Test code to reproduce

Import a component using a wrong path, i.e. if component is exported by default, use a named import

// component
import React from 'react'

const Example = () => (
  <span>
    "hello there"
  </span>
)

export default Example

// test
import React from 'react'
import { Example } from './example'

it('example', () => {
  cy.mount(<Example />)
})
