Fixes travis trying to install a travis package from pip

For some reason, this used to work because there was a pip package
called travis in there. They seem to have removed it now, and so `pip
install travis` breaks now. The `--user whoami` think ended up
generating a `travis` package, ignoring the `--user` part.
