fix broken basic auth for async calls (#917) 

* HTTP Basic Auth, some cleanups

There’s no need for additional dependency `btoa` as `XHR2` already has
the support for Basic Auth.

* remove redundant code

* fix semicolons

* Rewrite Basic Auth to support both sync and async calls.

* semicolon consistency
