fix: setAuthFromQueryParams checks for window var (rethinkdb#770)

* Fix, setAuthFromQueryParams() compatible with React Native (android)

`window` exists on Android but does not have a `location` property, so

* TMP fix for client to work in React Native (breaks the CLI)

* Revert "TMP fix for client to work in React Native (breaks the CLI)"
