We should stringify an empty jQuery element better

[bahmutov]

When throwing an error, I see the following

Which is due to code in $utils.stringifyActual(subject)

Debugging this I see an empty jQuery element.

We can definitely report a better message instead of {}

I will create a better reproducible example, right now this happens inside a custom command

Below is the reproducible example:

it('throws when not passed DOM element as subject', () => {
  cy.visit('fixtures/dom.html')
  cy.noop(cy.$$('#should-not-exist')).scrollTo('250px')
})

The code for this is done in cypress-io/cypress#14769, but has yet to be released.
We'll update this issue and reference the changelog when it's released.

Released in 6.7.0.
