Passing two arguments to cy.its() should throw an err to instead use cy.invoke()

[jennifer-shehane]

asserting off of a value on an attr in cy.its() is returns a function a Function instead of the actual value, need to throw error to the user that they really want to use cy.invoke().

Example Code

cy.get("img").its("attr", "src").should("match", /logo/)

Example Error

expected: [Function] to match /logo/

Example Code

cy.get("a").its("attr", "data-js").should("eq", "edit-company")

Example Error

expected: [Function] to eq "edit-company"
