bru command line treatment of "collection.bru" as a request in a collection

[dxxd116]

bru command will treat "collection.bru" as a request in a collection while it is actually a setting file for a request collection.
That results in a request is sent according to the specifications in the "collection.bru" file, which will fail eventually as there is no url settings inside it.

sample "collection.bru"

test("Response status code is 200", function () {
    expect(res.getStatus()).to.equal(200);
});


test("Response time is less than 10s", function () {
  expect(res.getResponseTime()).to.be.below(10000);
});
