'Nested' assertions not working in 3.4.1

[hannaofsweden]

Current behavior:
According to the documentation this should work:

expect({a: {b: ['x', 'y']}}).to.have.nested.property('a.b[1]')

(Or cy.something().should('have.nested.property, 'a.b[1]') )

However if you do that you will get:

TypeError: Cannot read property 'property' of undefined

Desired behavior:

Nested assertions should work as specified in the documentation.

Versions
Cypress: 3.4.1
Chrome: 74
Electron: 61

The nested was introduced in Chai 4.0.0. Cypress is currently using Chai 3.5.0.

This will be fixed in our breaking Cypress v4 release - I will be closing this issue as 'pending release' since the code for this is done, but has yet to be released.

• PR containing Chai update: Upgrade chai to latest version #2529
• Cypress v4 release (this issue will be fixed when this issue is closed): Cypress v4.0 #4270

I've confirmed that this works in upcoming 4.0 release. The code for this is done, but this has yet to be released. We'll update this issue and reference the changelog when it's released.
