Replace argue.js usage with inline argument checking

[murgatroid99]

This fixes #133 and #161. The error messages will be a little less helpful right now, but we can improve that later and I think it's good to get the fix out now.

The dependency on argue.js was actually removed a while ago in grpc/grpc#11707, but for some reason that change never made it out of the v1.4.x branch. So this is also correcting that error.

This causes requests to throw when options === undefined. If this is new, intended behavior it is a breaking change from argue.js's behavior. This caused quite the headache for me and my team, as we didn't think to look to the grpc lib originally, because we felt such a breaking change would not be in a minor version bump.

For reference, we were calling the client request as such:

function makeCall(rpc, message, meta, options) {
  return new Bluebird((resolve, reject) => {
    client[rpc](message, meta, options, (err, res) => {
        if (err) {
          return reject(err);
        }
        return resolve(res);
    });
  });
}

Giving the options argument a default of = {} resolved the issue, but I don't feel like this should be necessary.

Thank you for reporting this issue. It was also reported in #178 and a fix is in #179. We will try to publish a patch release soon after that is merged.
