When baseUrl is set, spawn cypress directly to this domain

[brian-mann]

In every single spec file, when Cypress first opens, it will open on localhost + a random port.

When Cypress begins processing the first spec file it will almost always encounter a cy.visit(...) to a different host and/or port.

This causes Cypress to change to the new host + port which is an unnecessary waste of time.

If baseUrl is set in cypress.json we should immediately open Cypress to this superdomain. This would avoid the initial page reload.

Fixed in 0.18.6.
