Use errorThreshold from global options

[nelson-amorim]

As described here, global options are only took in consideration if we pass an empty object as the second argument.

This PR intends to solve this issue passing the empty object as the default value for the params parameter.
With this we guarantee that the code bellow will work:

compareSnapshotCommand({
  capture: "fullPage",
  errorThreshold: 0.04,
});

cy.compareSnapshot("home"); // use global options errorThreshold (0.04)
cy.compareSnapshot("home", 0.03); // use 0.03 as errorThreshold
cy.compareSnapshot("home"); // use 0.0 as errorThreshold

This looks good to me. Are you still working on it?

It was on draft because I wanted to test it again before.
Tested again, working as expected.
