Open() does not throw error on inaccessible or invalid URL

[niallo]

Browser tests should fail in obvious cases like your server isn't running or you aren't on the right network. My suggestion is to check that the browser receives a valid response from the server.

Example test case to repro:

module.exports = {
  'Open should fail for bad URL but it does not': function(test) {
    test.open('foobar://BADURL.example').done();
  }
};

Output:

[asciidisco]

Good catch, we need to take care of that.
