Cypress.env() state is not reset on rerun of test

Current behavior:

Cypress.env() state is only read in once when the runner starts. This causes any changes to Cypress.env() to not reset when you rerun a test.

Desired behavior:

Clean, fresh Cypress.env() for each rerun of a test.

Steps to reproduce: (app code and test code)

{
  "env": {
    "num": 2
  }
}

it('should set ENV var num', () => {
  cy.log(`${Cypress.env('num')}`) // logs 2, but 3 on rerun
  Cypress.env('num', 3)
  cy.log(`${Cypress.env('num')}`) // logs 3
})

But if I rerun the test, the log is already 3 at the beginning.

Versions

Nice writeup, I’m hitting the same issue, with both Cypress.config and Cypress.env. This is still occuring in cypress@4.4.1.

The docs state that both env and config resets between both runs and test suites, neither of which is currently true.
