fix the travis uploading conda package

[crazyhottommy]

only two small edits:

1. add a build pass badge to the README.md
2. fix the conda uploading command in the .travis.yaml file.

let's see if it passes the build test or not.

It will pass since the after_success section won't affect the status. Let's see if we will have a new conda package in the channel after I publish an updated release.
