Unexpected error when stubbing a request with cy.intercept(string, { headers: {} })

[flotwig]

Current behavior

In Cypress 7, the cy.intercept(url, routeMatcher) overload was added. Now, when doing the following:

cy.intercept('/url', { headers: { foo: 'bar' }, body: '' })

or a variation, you get the following error:

When invoking cy.intercept() with a RouteMatcher as the second parameter, a handler (function or StaticResponse) must be specified as the third parameter. If you intended to stub out a response body by passing an object as the 2nd parameter, pass an object with a body property containing the desired response body instead.

Obviously this is not quite the case, since the object DOES have a body property.

Desired behavior

2nd argument is treated as StaticResponse in this case

This check: if (_.isString(matcher) && hasRouteMatcherKeys(handler)) { should probably do hasONLYRouteMatcherKeys(handler) to avoid this problem.
